Interquartile range

Using Mann-Whitney test, HCV RNA levels of female patients were significantly different (P < 0.05) from male patients.

Using Kruskal-Wallis test, Correction α is 0.025, HCV RNA levels were significantly higher (P < 0.025) in subjects aged above 40 than the subjects at age of 30 or below.

There were only two genotype 3a specimens which can be detected HCV RNA level, we excluded them in our statistics. Using Kruskal-Wallis test, Correction α is 0.025, HCV RNA levels were significantly higher (P < 0.025) in subjects with genotype 6a and 1a,1b infection than subjects with genotype 3b infection.
