Results of multivariate analysis (multiple Poisson regression) relating the total number of reported abstract items among 16 Consolidated Standards of Reporting Trials recommendations per considered randomised controlled trial publications (n=136) to general characteristics of the underlying journals; associations between violation counts and journal characteristics were quantified via incidence rate ratios (IRR) point estimates and the corresponding unadjusted two-sided 95% CI (CI lower and upper bound, respectively); unadjusted two-sided p values were derived from likelihood ratio tests and indicate locally significant associations in case of p≤0.05
