Comparison of HBsAg clearance rate in different baseline HBsAg level groups.

HBsAg (IU/ml)	HBsAg seroclearance group (N = 25)	HBsAg non-seroclearance group (N = 36)	HBsAg clearance rate	P
HBsAg < 100	17	15	53.13%	0.047
100 ≤ HBsAg < 500	6	7	46.15%
500 ≤ HBsAg < 1,000	2	11	15.38%
1,000 ≤ HBsAg	0	3	0%

P1 = 0.672 (HBsAg < 100 vs. 100 ≤ HBsAg < 500).

P2 = 0.02 (HBsAg < 100 vs. 500 ≤ HBsAg < 1,000).

P3 = 0.039 (HBsAg < 100 vs. 1,000 ≤ HBsAg).

P4 = 0.202 (100 ≤ HBsAg < 500 vs. 500 ≤ HBsAg < 1,000).

P5 = 0.408 (100 ≤ HBsAg < 500 vs. 1,000 ≤ HBsAg).

P6 = 0.344 (500 ≤ HBsAg < 1,000 vs. 1,000 ≤ HBsAg).
