aThe number needed to treat is the number of students who would have to receive Shamiri for one additional participant to have the specified outcome. When the incidence for the control condition is greater than Shamiri, it produces the number of people who would have to receive Shamiri to not have the specified outcome. These situations are represented with an asterisk. Numbers with a b were significant in a majority of the 7 imputed datasets
