Demographic and anthropometric factors in diabetic and healthy subjects with or without acanthosis nigricans
| Variable | Acanthosis nigricans (diabetic subjects/n = 150) | p Value | Acanthosis nigricans (non- diabetic subjects/n = 150) | p Value | ||
|---|---|---|---|---|---|---|
| Present n = 94 (62.6%) | Absent n = 58 (37.4%) | Present n = 60 (40%) | Absent n = 90 (60%) | |||
| The p value shows comparison with χ2 test for qualitative (categorical) variables and Student’s t test for quantitative (continuous) variables. BMI, body mass index; AN, acanthosis nigricans; WC, waist circumference; WHR, waist-hip circumference; SFT, skinfold thickness; IP, impedance plethysmograph; T2DM, type 2 diabetes mellitus. * p Value is significant. †Duration of type 2 diabetes mellitus in years. | ||||||
