^aTo the overall mean.

^bIf the QOL is better more than 5% compared to the overall mean, +1 point is given for every 5%, if the QOL is worse less than 5% compared to the overall mean, -1 point is given for every 5%.

In italicized items or subscales, higher score indicates better condition. In non-italicized items or subscales, higher score indicates worse condition.
