Values are averages with standard deviation in parentheses. Means within rows with different letters are significantly different (t-test, P < 0.05). nsnot significant. The total rating was interpreted as follows: very poor (≤10); poor (11–20); fair (21–30); good (31–40); and excellent (41–50) points.
