Key result
Statistical approaches using ordinal outcomes were significantly more efficient than binary tests for analyzing vascular events across 85 prevention trials (P<0.0001).
Why the study?
Does using ordinal outcomes improve statistical efficiency compared to binary outcomes in vascular prevention trials?
Meta-Analysis (n=335,305)
Does using ordinal outcomes improve statistical efficiency compared to binary outcomes in vascular prevention trials?
p-value: p=<0.0001
Analyzing vascular events using ordinal outcomes rather than binary outcomes improves statistical efficiency and could allow for smaller trial sizes.

Ordinal analysis may enable smaller vascular prevention trials; extends RCT evidence supporting ordinal over binary outcomes.
Bath et al. (2008) conducted a meta-analysis in Vascular prevention (n=335,305). Ordinal outcome analysis vs. Binary outcome analysis was evaluated on Efficiency of statistical tests (p=<0.0001). Statistical approaches using ordinal outcomes were significantly more efficient than binary tests for analyzing vascular events across 85 prevention trials (P<0.0001).
