Figure 2From: Contrasting effects of preexisting hyperglycemia and higher body size on hospital mortality in critically ill patients: a prospective cohort study Adjusted hazard ratio at various BMI levels. The risk of hospital mortality is found when the hazard ratio expressed as mean (empty circle) and 95% confidence interval (dashed lines) do not cross 1. A hazard ratio >1 is indicative of increased risk for those with BMI lower than that chosen for analysis.Back to article page
