Table 2 Comparison between HBV DNA PCR results in the studied patients

N = 200		At the start of treatment	After 1 month of treatment	At the end of treatment	P-value
HBV DNA PCR	Negative	166 (83%)	159 (79.5%)	154 (77%)	P1 = 0.253 NS P2 = 0.064 NS P3 = 0.475 NS
HBV DNA PCR	Positive	34 (17%)	41 (20.5%)	46 (23%)	P1 = 0.253 NS P2 = 0.064 NS P3 = 0.475 NS

X²: chi-square test
S: p-value < 0.05 is considered significant
HS: p-value < 0.001 is considered highly significant
P1: refers to the statistical difference between the start of DAA and 1 month after DAA
P2: refers to the statistical difference between the start of DAA and the end of DAA
P3: refers to the statistical difference between 1 month after DAA and the end of DAA
