PMID: 24589872 We applied cohort- specific Cox proportional hazards models using a standardized protocol.

We applied cohort- specific Cox proportional hazards models using a standardized protocol.

Univariate and multivariate cause- specific Cox proportional hazards analysis were performed.

Hazard ratios were estimated using sex- specific Cox models, stratified by cohort, with age as the time scale.

Objective: To investigate the underlying mechanism of apoptosis-inducing effect of a specific COX-2 inhibitor SC236 in gastric cancer cells.
