This study aims to compare nested case-control and Cox regression methodologies for analyzing time-dependent exposures.
Analyzed a cohort of 1340 subjects with multiple time-dependent covariates.
Repeated nested case-control analyses for varying controls per case (4, 8, 16, 32, 64).
Compared computational efficiency of nested case-control versus Cox regression using CPU time.
Results from nested case-control analyses were similar to those obtained using Cox regression.
Cox regression was 125 times slower than the nested case-control approach with four controls.
The nested case-control method proved to be more efficient, particularly in databases with rare outcomes.
