Background
Primary objective: To identify, classify and quantify outcome measures used in randomised controlled trials of immunomodulatory therapies for non-infectious uveitis, and assess whether risk of bias was associated with trial success.
Secondary objectives: To describe the components of composite efficacy outcomes, examine how outcome type relates to Cochrane Risk of Bias 2 assessments, and explore variation by uveitis subtype, trial phase and intervention class.
Method
Study Selection
1,259 records identified
100 randomised controlled trials included
742 outcomes analysed
FIGURE 1. Outcome classification framework
Outcomes were grouped into seven efficacy or safety domains, then classified by the specific variable measured. Similar outcome definitions were further grouped into shared subcategories to enable comparison across trials.
FIGURE 2. Frequency of outcome measures across domains
Of the 742 outcomes, 599 were efficacy-focused and 143 were safety-focused. Efficacy outcomes most commonly assessed disease activity, tissue damage, visual function, concomitant medication use, and patient-reported outcomes.
Composite Endpoints
64/100 trials used composite efficacy endpoints
124 composite efficacy outcomes identified
24 different composite types
33% were based on non-specific clinical opinion
FIGURE 3. Distribution of risk of bias ratings across outcome categories (A) Frequency and proportion of low- and high-risk of bias ratings across outcome categories. (B) Distribution of high-risk of bias judgements across individual Cochrane RoB2 domains.
Out of 742 outcomes, 116 were low risk of bias, 626 were high risk. Composite efficacy outcomes were high risk in 98.4% of cases, and vitreous haze outcomes in 100%. Bias in outcome measurement was the most common single driver of high-risk ratings.
