It is convex for decreasing hazards and concave for increasing hazards leading to a single-Weibull model.
Our analysis, with adjustment for potential confounding factors, indicates a 54% increased hazard for progression from NPDR to PDR in patients with nonhealing ulcers.
After adjustment for covariates, acute kidney injury was still associated with an almost twofold increased hazard for hospital mortality (Table 5, panel A).
Hazard ratios for train drivers were close to 1. Significant increased hazard ratios for acute myocardial infarction and for sub-acute and chronic coronary heart disease were observed for shunting yard engineers.
Using Cox proportional hazards modeling that incorporated transfusion as a time-dependent covariate and adjusted for baseline characteristics, bleeding, transfusion propensity, and nadir hematocrit, transfusion was associated with an increased hazard for 30-day death (adjusted hazard ratio [HR], 3.94; 95% confidence interval [CI], 3.26 4.75) and 30-day death/MI (HR, 2.92; 95% CI, 2.55 3.35).
In the sensitivity analyses, AKI was not associated with an increased hazard for three-year mortality.
After adjusting for age, comorbidities, and characteristics of ICU admission and treatment, AKI was not associated with an increased hazard for 3-year mortality (Table 2).
The aim of our review was to evaluate the evidentiary base supporting the hypothesis that the increased hazard for metabolic disturbance in MDD subpopulations (and vice versa) is mediated in part by endophenotypic variations in sleep architecture.
If it proves true that they are indicative of CV risk in migraine, these WMHs, by revealing the presence of subclinical organ damage, could be a useful marker in migraineurs to evaluate the increased hazard for CV events as well as the presence of carotid intima-media thickening and atherosclerosis in the general population.
