Evolution of Health-Related Quality of Life (HRQoL) scores

Whole sample n = 5,727	HRQoL before infection (a)	HRQoL at time of infection (b)	HRQoL 3 months after infection (c)
	Weighted Mean (SD)	Weighted Mean (SD)	Weighted Mean (SD)
	0.92 (0.11)	0.80 (0.18)	0.91 (0.13)
Minimal detectable change (MDC)a	0.113	Meets MDC criterion	Does not meet MDC criterion

^aAt the 95% confidence level, MDC = SEM × √2 × 1.96, with the SEM = ${\sigma }_x\ast \sqrt{1-r_x}$, (r_x = 0.86)
