['The aim of this study was to define the effect of statin on 30-day mortality in an oriental population with sepsis.', 'We conducted a retrospective study on patients with sepsis at National Taiwan University Hospital from 2001 to 2002. The effects of statins on 30-day mortality were evaluated based on clinical settings. Log-rank test and Cox regression analysis were performed using the proportional hazards assumption.', 'A total of 763 episodes of sepsis were reviewed; 454 consecutive patients were considered eligible. Among them, 104 (22.9%) took a statin at least 30 days before admission and during sepsis course, whereas the other 350 control (77.1%) did not. There was no significant difference of 30-day sepsis-related mortality between groups (19.2% vs 18.9%, P = .952). Statin treatment was not associated with decreased mortality at 30 days (P = .853; risk ratio, 0.95; 95% confidence interval, 0.53-1.68).'] Do statins improve short-term survival in an oriental population with sepsis?
