Abstract

BackgroundPain is the most troubling issue to patients with osteoarthritis (OA), yet current pharmacological treatments offer only small-to-moderate pain reduction. Current guidelines therefore emphasise the need to identify predictors of treatment response. In line with these recommendations, an individual patient data (IPD) meta-analysis will be conducted. The study aims to investigate the relative treatment effects of topical non-steroidal anti-inflammatory drugs (NSAIDs) and topical capsaicin in OA and to identify patient-level predictors of treatment response.MethodsIPD will be collected from randomised controlled trials (RCTs) of topical NSAIDs and capsaicin in OA. Multilevel regression modelling will be conducted to determine predictors for the specific and the overall treatment effect.DiscussionThrough the identification of treatment responders, this IPD meta-analysis may improve the current understanding of the pain mechanisms in OA and guide clinical decision-making. Identifying and prescribing the treatment most likely to be beneficial for an individual with OA will improve the efficiency of patient management.Systematic review registrationCRD42016035254Electronic supplementary materialThe online version of this article (doi:10.1186/s13643-016-0348-8) contains supplementary material, which is available to authorized users.

Summary

Discussion

An IPD meta-analysis forms a part of precision medicine It helps identify potential predictors of treatment response at a patient level, which is not possible with conventional meta-analyses. It is very difficult to acquire data for a specific question from all studies, especially data related to subgroup indicators This limits the IPD analysis to predictors that are available in the eligible studies. It may not be possible to contact original trial authors, authors may not be willing to collaborate, or they may not have access to the raw data required [45, 46] These difficulties, if not overcome, may introduce bias to the meta-analysis if the studies not included are systematically different from those included [45,46,47].
