Introduction. Hyperlipidemia is an underlying process behind cardiovascular disease. Chinese medicine (CM) may be effective in treating hyperlipidemia, but there is a lack of studies with high methodological quality. A major reason for this is heterogeneity in outcome reporting. Therefore, this study explores the degree of outcome reporting variation in CM trials for hyperlipidemia. It then generates a list of potentially important outcomes for developing a core outcome set (COS). Methods. A systematic review of literature focusing on studies of CM for hyperlipidemia was conducted. Outcomes were listed verbatim and grouped into 8 domains. Outcome frequency and definition uniformity were analyzed. Results. 3,702 studies and 452 individual outcomes were identified. These outcomes were reported 27,328 times, of which 1.6% were reported as primary outcomes, and 13.3% were defined. The most frequent outcome was total triglyceride, represented in 86.7% of the studies, followed by total cholesterol (86.0%), total effective rate (75.1%), high-density lipoprotein cholesterol (73.2%), and low-density lipoprotein cholesterol (60.5%). However, 43.6% of outcomes were reported only once. The largest outcome domain was “pathological or pathophysiological outcomes,” which included 67.0% of outcomes. Of the “response rate related outcomes” domain, total effective rate was the most frequently reported outcome (n = 2,780), and 95.3% of the studies gave a clear definition. However, these definitions were often contradictory. Only 10 papers reported cardiovascular events, 3 of which referred to them as primary outcomes. Moreover, ten patient-reported outcomes were reported in the retrieved literature 19 times in total. The majority of the outcomes did not report measurement instruments (MIs) (269/453, 59.4%). MIs of the surrogate outcomes were reported more frequently. Conclusion. Outcome reporting in CM trials for hyperlipidemia is inconsistent and ill-defined, creating barriers to data synthesis and comparison. Thus, we propose and are developing a COS for CM trials for hyperlipidemia.

IntroductionMyocardial infarction (MI) is the most dangerous complication in patients with coronary heart disease. In China, there is an increasing number of randomised controlled trials (RCTs) of traditional Chinese medicine (TCM) for treating MI. However, the inconsistency of outcome reporting means that a large number of clinical trials cannot be included in systematic reviews to provide the best evidence for clinical practice. The aim of this study is to develop a core outcome set (COS) for future TCM clinical trials of MI, which may improve the consistency of outcome reporting and facilitate the synthesis of data across studies in systematic reviews.Methods and analysisWe will conduct a systematic review of MI clinical trials with any intervention. Semistructured interviews will be conducted to obtain the perspectives of patients with MI. The outcomes from the systematic review and semistructured interviews will be grouped and used to develop a questionnaire. The questionnaire will be developed as a supplement for the TCM syndromes of MI and will be constructed from the results of a systematic review, existing medical records and a cross-sectional study. Then two rounds of the Delphi survey will be conducted with different stakeholders (TCM experts and Western medicine experts in cardiovascular disease, methodologists, magazine editors and patients) to determine the importance of the outcomes. Only the TCM experts will need to response to the questionnaire for core TCM syndromes. A face-to-face consensus meeting will be conducted to create a final COS and recommend measurement time for each outcome.Ethics and disseminationThis project has been approved by the Ethics Committee of Dongzhimen Hospital, Beijing University of Chinese Medicine. The final COS will be published and freely available.Trial registration numberThis study is registered with the Core Outcome Measures in Effectiveness Trials database as study 1243 (available at:http://www.comet-initiative.org/studies/details/1243).

ObjectiveTo identify what outcomes have been assessed in traumatic brachial plexus injury (TBPI) research to inform the development of a core outcome set for TBPI.DesignSystematic review.MethodMedline (OVID), EMBASE, CINAHL and AMED were systematically searched for studies evaluating the clinical effectiveness of interventions in adult TBPIs from January 2013 to September 2018 updated in May 2021. Two authors independently screened papers. Outcome reporting bias was assessed. All outcomes were extracted verbatim from studies. Patient-reported outcomes or performance outcome measures were extracted directly from the instrument. Variation in outcome reporting was determined by assessing the number of unique outcomes reported across all included studies. Outcomes were categorised into domains using a prespecified taxonomy.ResultsVerbatim outcomes (n=1491) were extracted from 138 studies including 32 questionnaires. Unique outcomes (n=157) were structured into 4 core areas and 11 domains. Outcomes within the musculoskeletal domain were measured in 86% of studies, physical functioning in 25%, emotional functioning in 25% and adverse events in 33%. We identified 63 different methods for measuring muscle strength, 16 studies for range of movement and 63 studies did not define how they measured movement. More than two-thirds of the outcomes were incompletely reported in prospective studies.ConclusionThis review of outcome reporting in TBPI research demonstrated an impairment focus and heterogeneity. A core outcome set would ensure standardised and relevant outcomes are reported to facilitate future systematic review and meta-analysis.PROSPERO registration numberCRD42018109843.

Abstract Background Traditional Chinese medicine (TCM) plays an important role in contributing to the public health in China. However, non-standardized outcomes in TCM related studies posed great difficulty in data synthesis for healthcare decisions. An agreed set of standardized outcomes, or termed as a core outcome set (COS), can solve this existing problem of outcome heterogeneity. This review aimed to analyze outcome heterogeneity, assess the quality of outcome reporting and providing a list of potential outcomes for COS development of SAP using TCM. Methods 8 literature databases were searched to identify clinical studies about TCM for SAP (SAP-TCM) of yearly samples of 2005, 2010, 2015, 2016, 2018 and 2019. 2 clinical registry databases were searched from inception to October 2020. Outcomes definition, measurement methods and time-point were extracted and categorized into 7 themes which include clinical symptoms and signs, physical and chemical examination, TCM-related outcomes, adverse events, quality of life, long-term prognosis and economic evaluation. Timing and quality assessment of the outcomes reported were analyzed and evaluated. Results A total of 1166 studies were included from 12962 potential studies, involving 111426 patients. 231 outcomes were identified and a total of 89 outcomes reported at least twice in the studies. The most commonly reported theme was clinical symptoms and signs. The most frequently reported outcomes were total rate of ECG efficiency and angina attack in clinical studies of published literature and clinical registries databases respectively. Outcomes reported in a single study ranged from 1 to 15, and 5 outcomes on average per study. 80% of the studies lack reporting of primary outcomes. A wide variation of measurement instruments or methods was used. A range of 1–17 measurement time-points were recorded. Quality assessment of outcome reporting was generally low, with 65.6% of the studies scoring 3 to 4 points. Conclusion Outcomes reported in studies on SAP-TCM are heterogeneous. A lack of standardization complicates comparisons of outcomes across studies. Developing a COS for SAP-TCM could contribute to the standardization of outcome reporting and offer a stronger evidence for health decision-making.
