Misclassification of obesity using BMI compared with DEXA and association with sarcopenia. Misclassification of obesity using BMI compared with DEXA and association with sarcopenia. A shows the prevalence of obesity by creatinine-based eGFR categories. DEXA-defined obesity on the basis of total body fat percentage was used as the standard for obesity (obese by DEXA). Among these participants, if they were also obese by BMI (BMI≥30 kg/m2), they were classified as obese by DEXA and BMI. If they were not obese by BMI (BMI<30 kg/m2; i.e., they were misclassified by BMI as not obese), they were classified as obese only by DEXA (not BMI). B shows the prevalence of sarcopenia by creatinine-based eGFR categories among participants who were obese by DEXA and BMI, were obese only by DEXA (not BMI), and had BMI≥30 kg/m2 (obese by BMI [regardless of DEXA]). Error bars represent SEMs. The denominator for all percentages is the total number of participants within each respective eGFR category. Deep Sharma et al.
