Fig 2 Box plots of quality of life scores by CEAP clinical class. Higher class, more severe clinically assessed CVD. A, Short-Form Health Survey (SF-36) Physical Component Summary score (PCS). B, SF-36 Mental Component Summary score (MCS). C, VEINES QOL score. D, VEINES-Sym. For all QOL measures, lower scores indicate poorer quality. For SF-36 PCS and MCS, data available for 1320 (86.2%) study subjects; for VEINES-QOL and VEINES-Sym, data available for 1436 (93.8%) and 1422 (92.9%) study subjects, respectively. P value for trend: SF-36 MCS, P = .29; SF-36 PCS, P < .0001; VEINES-QOL, P < .0001; VEINES-Sym, P < .0001. +, Mean QOL score; horizontal lines, median score; boxes, interquartile range; lines above and below boxes, range.
