CD4 and tuberculosis: Children with an ERC-adjudicated incident TB diagnosis were marginally more likely to be aged <3 years at ART initiation (45 % vs. 34 % without TB, P = 0.07), and to be female (59 % vs. 49 %, P = 0.09); they were significantly more likely to have a lower CD4 percent (median 8 % vs. 13 % for those without TB, P <0.001), lower height- and weight-for-age Z scores (median −3.0 and −2.8, respectively, vs. −2.3, and −1.8, respectively, both P <0.001); and to already have WHO stage 3 or 4 HIV disease (75 % vs. 62 %, P = 0.03) at ART initiation.
