In the 3340 participants who remained in the analysis after the first year
(because no one in their quintuplet had died), 24.6% (n=164) of hip fracture cases and
21.9% (n=585) of controls died by year 5 [OR 1.2 (1.0, 1.5)]; the association was no longer
significant after adjusting for potential confounders [1.2 (0.9, 1.5)].
