Logistic regression procedures were performed to estimate odds ratios (OR) and 95% confidence intervals (95% CI) adjusted for confounders.
However, among smokers, greater pack per day of smoking history was associated with higher odds of glaucoma after adjusted for confounders.
The association between maternal exposure to terror attacks during pregnancy and the risk of schizophrenia in the offspring was quantified with relative risks (RR) and their 95% confidence intervals (CI) fitting Cox regression models unadjusted and adjusted for confounders.
All outcome analyses were adjusted for confounders.
Cox regression methods were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) adjusted for confounders.
a The observed group means, and their standard deviations (SD) and group differences are not adjusted for confounders.
Odds ratios (OR) [with 95% confidence interval (CI)] were calculated by logistic regression analyses and adjusted for confounders.
All statistical models were extensively adjusted for confounders, including comorbidity, admission diagnosis, other electrolytes and acid base parameters.
When the whole cohort was included in a time-stratified model (Additional file 1: Table S6), AKI adjusted for confounders was a significant risk factor for mortality in the time period from ICU admission to 30 days, but not thereafter.
Logistic regression adjusted for confounders (diet soda, age, race-ethnicity, gender, poverty).
Most studies were not adjusted for confounders and the heterogeneity across studies precluded the calculation of a meaningful overall summary measure.
