Median NT‐proBNP was 305 pg/mL (132–906) in those underweight, 204 pg/mL (85–634) in those with healthy weight, 145 pg/mL (61–421) in those overweight, 119 pg/mL (51–134) with obesity class I, 104 pg/mL (49–265) with class II and 101 pg/mL (47–245) for those in class III (Table2). Here, NPPB is linked to obesity due to melanocortin 4 receptor deficiency.
