a
The present data show the relative risk for the binary outcome hair loss and the odds ratios for the continuous outcome Norwood-Hamilton scale per standard deviation increase including 95% CIs. No significant associations were observed.
b
The multivariable model was adjusted for age, waist circumference, smoking status (3 categories), alcohol consumption, diabetes mellitus, and hypertension.
