Data entry and statistical analysis
The recorded responses were exported to Microsoft (MS) Excel except in one school where data was collected through offline forms and entered manually into MS Excel. The data entry was done simultaneously on the same day of the collection of data by the principal investigator. Statistical analysis was done using International Business Machines (IBM)—Statistical Package for social sciences (SPSS) version 26. Descriptive data on socio-demographic details of students are presented in percentage or proportion. Quantitative variables such as the age of the students are expressed as mean and standard deviation. To assess the effectiveness of the intervention, the proportion of students in KAP of all domains was considered. The proportional change was measured among the intervention and control groups before and after the intervention by using the Chi-square test. With the cells having a count less than five, Fischer exact test was used. A p-value of < 0.05 was considered significant.
