Median NT-proBNP-levels (25–75 percentiles) at baseline and after gastric bypass surgery (n = 71) and lifestyle intervention (n = 62). p values indicate significant changes within and between the intervention groups. The grey background represents the 25–75 percentile for the NT-proBNP levels in the normal weight healthy reference group (n = 30)
