Difference in means between groups was evaluated by analysis of variance. As CRP did not have normal distribution it was summarized as median (range), and comparison among groups was made by Kruskal–Wallis test. Categorical data were presented as percentages and compared among groups by χ2 ...

RESULTS: When analyzed via Cox proportional hazard regression, the relationship between BMI and mortality, represented by means of hazard ratio, was clearly U-shaped for both men and women. The base of the curves was fairly wide suggesting that a broad range of BMIs are well tolerated by ...

The sensory and mixed nerve amplitudes correlated significantly (P 0.01) with BMI for all nerves tested, with means being approximatly 20–40% lower in the obese than in the thin subjects. No correlation was noted between BMI and nerve conduction velocity, H-reflex latency, or most of the ...
