Fig. 1. From: Effect of comorbidity on quality of life of male veterans with prevalent primary total knee arthroplasty.

Effect of number of comorbidities (none, one, two, three, or more) on SF-36 V domain and summary scores in men with primary TKA. SF-36 V scores were significantly lower in patients with primary TKA that have higher comorbidity for all eight subscales (all p values<0.001), PCS (p value<0.001), and MCS (p value<0.001). These analyses were adjusted for age, duration since TKA, and five common comorbidities (COPD/asthma, diabetes, depression, hypertension, heart disease). Scores for each domain and summary scale range from 0 to 100 with a higher score indicating better health. PCS and MCS are norm-based with a mean of 50 and standard deviation of 10 for the US general population. Error bars represent standard error of the mean. PF physical functioning, RP role physical, BP bodily pain, GH general health, VT vitality, SF social functioning, RE role emotional, MH mental health, PCS physical component summary, MCS mental component summary
