CRP and tuberculosis: The first data set (data set 1) includes Age, Gender, neutrophil and lymphocyte count, NLR, TB, CRP, AppD, and PALC, which were significant in the univariate analysis as input parameters/features, whereas the second data set (data set 2) only included Age, CRP, and PALC, which were found to be independent factors for perforation in the multivariate analysis.
