SF-36 scores. a The SF-36 norm-based scores in each dimension for the blind group, severely impaired group, and the published Japanese standard for young males. The solid horizontal line at a norm-based score of 50 indicates the general Japanese standard (with a standard deviation of 10). No between-group (blind vs. severely impaired subjects) differences were found. The Physical Function scores of the severely impaired subjects and the Vitality scores of the blind subjects were higher and lower, respectively, than the general Japanese standards [50; indicated by asterisks (*)]. The Vitality scores of the blind subjects were also lower than the Japanese standard for young males [indicated by the number sign. (#)]. b Norm-based SF-36 scores in each component summary score. The horizontal line and legends are the same as in (A). No differences were found in any of the comparisons. PF: Physical Function, RP: Role Physical; BP: Bodily Pain; GH: General Health; VT: Vitality; SF: Social Function; RE: Role Emotional; MH: Mental Health; PF: Physical Function; PCS, MCS, and RCS: Physical, Mental, and Role/Social Component Summary Scores, respectively
