Figure 1 Proportions of subjects with hematuria and circulating hemoglobin levels according to body mass index (BMI) categories. (a) The upward (men) and downward (women) triangles indicate the mean percentage of subjects with hematuria (≥ +1 on dipstick urinalysis) according to BMI intervals (2.0kg/m2), and was calculated for each BMI interval as follows: mean percentage=(number of subjects with proteinuria)/(number of subjects in each BMI group) × 100. The vertical bars represent the standard error when proteinuria is coded as 1 and non-proteinuria is coded as 0. The number of subjects was 204, 565, 1026, 1044, 665, and 539 for men, and 248, 501, 539, 361, 168, and 171 for women for the BMI categories from ≤18.9 to ≥27.0kg/m2. (b) The circles (proteinuria) and squares (non-proteinuria) represent the mean hemoglobin values in each BMI category. The vertical bars represent the standard error. The number of subjects was 116, 159, 242, 241, 216, and 336 for proteinuria, and 4743, 11,396, 15,857, 13,958, 8669, and 6649 for non-proteinuria for the BMI categories from ≤18.9 to ≥27.0kg/m2. The hemoglobin level was significantly higher in subjects with proteinuria than in subjects without proteinuria (P<0.0001; two-way analysis of variance).
