Figure 2.

Radar chart of change in Medical Outcomes Survey-Short Form (SF)-36 subscales comparing the control group (grey shade) with exercise alone (red shade; left panel), diet alone (yellow shade; middle panel), and exercise plus diet (blue shade; right panel)

Each point around the octagon represents an SF-36 subscale, each octagonal ring represents a three-point change in the outcome measure, the lines of each colored shape intersect the octagonal rings that correspond to the change from baseline to week 52. PF, physical functioning; RP; role—physical; BP, bodily pain; GH, general health; VT, vitality; SF, social functioning; RE, role—emotional; MH, mental health. The negative value of role physical for exercise (−2.05) was truncated to zero to facilitate comparison between groups.
