Because patients who are treated in tertiary hospitals are rarely discharged or transferred to another hospital, we believe that the 30-day mortality calculated from our cohort with longer hospital stays does not exceed the in-hospital mortality.
Main outcome measures Changes in breast cancer mortality calculated from linear regressions of log transformed, age adjusted death rates.
This was even more remarkable since predicted mortality calculated from the APACHE II score was significantly lower in patients with spontaneous hypothermia.
A second analysis was performed to explore the effect of angiopoietin concentrations on 30-day mortality, calculated from the day of fever onset.
Since the observed effect on mortality of ICU admission varied with the severity of illness (as measured by SAPS II), the analyses were stratified by categories of predicted mortality, calculated from the SAPS II score [ 11].
Hospital mortality ratios (95% confidence interval) [ 28] were 0.65 (0.48–0.87) and 0.69 (0.51–0.92), as compared with the expected mortality calculated from APACHE II and SAPS II scores, respectively.

Hospital mortality and overall mortality (overall mortality was calculated from the total expired patients including readmission and death thereafter) also were higher in the CA-AKI patients than in patients without CA-AKI (53.8% vs. 35.7%; OR, 2.1; 95% CI, 1.16 3.82; p = 0.019/ 55.8% vs. 38.2%; OR, 2.04; 95% CI, 1.12 3.71; p = 0.021, Chi-square test) (Table 4 ).
Data on risk of mortality from medical interventions were taken from systematic reviews or large observational studies, and, if needed, mortality was calculated from the rate of the adverse events and the known or estimated mortality rate from that event.
This study was a retrospective cohort study of drowning-related injury mortality incidence calculated from the annual and multi-year ACS data cycles.
Analyses were conducted for each sex separately and sexes were combined when appropriate Hazard ratios (HR) of mortality were calculated from Cox proportional hazard models with years since the examination in 1999 02 as time axis, so that individuals were considered at risk from 1999 02 until time at death, emigration/disappearance or April 27 2008, whichever came first.
One-month mortality was calculated from day of admission.
