Table 4. Pearson correlation coefficients among HRQoL domains, total number of conditions, number of infectious conditions, and number of non-infectious conditions, after controlling for age and gender.

Domain	Number of Conditions	Number of Infectious Conditions	Number of Non-Infectious Conditions
Overall Health (EQ VAS)	-0.060 [-0.073, -0.046]	0.051 [0.037, 0.064]	-0.124 [-0.137, -0.110]
Mobility	-0.032 [-0.045, -0.018]	0.097 [0.084, 0.110]	-0.134 [-0.147, -0.121]
Pain/Discomfort	-0.042 [-0.055, -0.028]	0.073 [0.060, 0.086]	-0.125 [-0.138, -0.112]
Self-Care	-0.025* [-0.038, -0.011]	0.082 [0.069, 0.095]	-0.111 [-0.125, -0.098]
Usual Activity	-0.045 [-0.059, -0.032]	0.080 [0.066, 0.093]	-0.136 [-0.149, -0.123]
Anxiety/ Depression	-0.048 [-0.062, -0.035]	0.041 [0.028, 0.054]	-0.102 [-0.115, -0.089]

* p = 0.002; all other ps < 0.001.

Note. Given our sample size and the generally high intercorrelations between HRQoL measures (Cronbach’s α = 0.86) and number of conditions (α = 0.69), differences between coefficients of a magnitude ≥ 0.017 were associated with a p-value < 0.05.
