- Comparisons were made based on the patients with microscopy data. The percentage of specimens that were AFB positive was compared between those that grew strains with either spoligotype SIT 17 or SIT 53, and those from which strains with all other patterns were isolated. Comparisons were made for all specimens in the study, and separately, for those obtained in Caracas (CCS). Two by two table comparisons with odds ratios and Yates corrected two-tail chi square values were calculated using OpenEpi http://www.openepi.com. Statistically significant p values are shown in bold
