WebApr 6, 2024 · The Chi-square test (X 2) was done to test the association between practices of respondents towards rabies and their sociodemographic characteristics. In case the assumptions of the Chi-square test were violated, Fisher’s Exact Test (FET) for a 2 × 2 contingency table and likelihood ratio (LR) for tables bigger than 2 × 2 tabulation was used. WebMethods: This study was conducted on 116 students assigned to intervention (n = 58) and control groups (n = 58). Data were collected at baseline and on months 6, 12 and 15 after the intervention. Multivariate analysis of variance, t-test with Bonferroni correction and Multi-chi-square test were used for repeated measurements.
