Re-analysis showed no difference in meta-analytic effect estimates before and after adding the new trial results, with a combined ratio of risk ratios of 1.00 (95% CI 0.99–1.01) and a combined difference in standardized mean differences of 0.01 (95% CI −0.04 to 0.06).
Re-analysis showed no difference in meta-analytic effect estimates before and after adding the new trial results, with a combined ratio of risk ratios of 1.00 (95% CI 0.99–1.01) and a combined difference in standardized mean differences of 0.01 (95% CI −0.04 to 0.06). The findings suggest that while searching registers identifies more trials, the current lack of timely result posting limits their impact on meta-analytic conclusions, highlighting a need for better trialist compliance.
