Figure 1. Cumulative Incidence of Heart Failure According to Categories of Body-mass Index (Panel A) and Vigorous Physical Activity (Panel B) at the Base-line Examination.

Body mass index is weight in kilograms (kg) divided by the square of the height in meters (m²). The body mass index was <25 kg/m² in lean participants, 25 to 29.9 kg/m² in overweight participants, and ≥30 kg/m² in obese participants. Active participants vigorously exercised for at least 1 to 3 times a month and inactive participants rarely/never exercised vigorously. Vertical bars represent 95% confidence intervals for the cumulative incidence.
