Improved estimates of floating absolute risk
Witryna25 lut 2024 · Hazard ratios (HRs) and 95% CIs were estimated using floating absolute risk. The floating approaches allow acceptable comparisons between any 2 exposure groups, which decreases undesired correlation between coefficients. 28-30 Model 1 was age-adjusted.
