The effectiveness of intervention in hepatitis C patients and improvement in their referral rate

Figures & data

Figure 1. The specific data of 638,308 cases were tested for anti-HCV in our hospital.

Chi-square test
Pearson = 33.015; p value = .000; p < .05
Likelihood ratio = 32.127; p value = .000; p < .05

^a The missed column is the amount of data with missing information in the collected basic data, which is not summarized and meaningless.

	N	Event	Sample p
Pre-intervention	5552	2078	0.374
