Article B Results. Ten out of 19 studies showed a significant reduction of SSI incidence (George et al., 2016). Moreover, in four out of these 10 studies, subjects received the “preoperative universal decolonization” with CHG and mupirocin and a substantial decrease in SSI was noted in non-general surgery cases (i.e. cardiac and orthopedic surgery) (George et al., 2016). One study had to be deleted due to use of other skin antimicrobial agents and CHG was used for oral rinse instead (George et al., 2016). Validity.

This finding is the part where the author thinks that the non-randomization of samples could have affected the study outcome. The additional one person who developed SSI despite undergoing decolonization treatment in the study group resulted in a 10.1% difference in the effectiveness measurement. This result looks very significant if one looks at it percentage-wise, but when looking at the actual numbers 10 SSIs out 21 treated subjects in the study group and nine SSIs out 24 untreated subjects in the control group, it will raise a red flag that there could have been a possibility for bias since the results are too close. Validity. Article C authors assigned subjects to the control and study group depending on the surgical unit that they were under (Sasi et al., 2015). According to Sasi et al. (2015), there are four surgical units involved in their study. Patients on the third surgical unit were taken as the study group because it was the unit that had the most number of
