ɣ value is derived from Pearson’s chi-square test; ‡ value from nonparametric median test. TB: tuberculosis; WBC: white blood cell count; MCV: mean corpuscular volume; CD: cluster of differentiation; IQR: interquartile range. †Cutoff ranges are according to Ugandan population estimate [21]; ß×103 cells per microliter; §grams per deciliter; femtoliters.
