The predictive validity of these scales for mortality varied: for instance, hazard ratios/odds ratios (95% confidence interval) for mortality risk for frail relative to non-frail people ranged from 1.21 (0.78; 1.87) to 6.03 (3.00; 12.08) for the Phenotype of Frailty and 1.57 (1.41; 1.74) to 10.53 (7.06; 15.70) for the Frailty Index.
When we adjusted the logistic regression model for occurrence of mild hypoglycemia with a cutoff value of 4.7 mmol/L, which is also independently associated with mortality [ 17], the OR (95% confidence interval) for ICU mortality in the lowest glucose stratum remained significant (medical: 2.6 [1.6 to 4.4], P < 0.001; surgical: 4.9 [1.1 to 22.1], P = 0.04).
A conditional logistic regression model was used to calculate odds ratio and 95% confidence interval for mortality recorded in HW compared with that recorded in nHW days pooled and stratified by duration of exposure, age of cows, and month of occurrence.
Compared with those with ≤1 nondisease-specific problems, multivariable adjusted hazard ratios (95% confidence interval) for mortality were 1.26 (1.19 to 1.32), 1.40 (1.33 to 1.48), and 1.66 (1.57 to 1.76) for 2, 3, and 4-6 nondisease-specific prespectivelypectively.
Relative risks with 95% confidence interval for mortality were calculated.
Using Cox regression, risk was estimated per 1-SD increase in QTc interval as well as prolonged QTc interval (>450 ms) vs. normal QTc interval for mortality.
Data presented as relative risks (95% confidence interval) for mortality; and as the standardized mean difference (95% confidence interval for cardiac index, norepinephrine reduction, oxygen delivery, oxygen consumption, and gastric PaCO2 gap.
The overall cohort relative risk (95% confidence interval) for mortality adjusted for sociodemographic characteristics (including individual socioeconomic status) was 1.08 (1.06 to 1.10) per 0.05 unit increase in Gini (fig 1).
Relative to the non-frail class, the age-adjusted Odds Ratio (with 95% Confidence Interval) for mortality at Wave 2 was 2.1 (1.4 - 3.0) in the pre-frail and 4.8 (3.1 - 7.4) in the frail.
Results are summarised in table 7. The odds ratios (95% credible interval) for mortality for active treatment compared with control were 0.74 (0.63 to 0.86) for selective digestive decontamination, 0.82 (0.62 to 1.02) for selective oropharyngeal decontamination, and 1.23 (0.99 to 1.49) for chlorhexidine (table 7).
Compared to those without the MDS or CMS-2728 NH indicator (No MDS/No 2728), multivariable adjusted hazard ratios (95% confidence interval) for mortality associated with NH status were 1.55 (1.46 – 1.64) for MDS/2728, 1.48 (1.42 – 1.54) for MDS/No 2728, and 1.38 (1.25 – 1.52) for No MDS/2728.
