Table 4 Baseline characteristics of clinically diagnosed versus bacteriologically confirmed TB patients (N = 157)

From: Why being an expert – despite xpert –remains crucial for children in high TB burden settings

  Clinically diagnosed TB (possible + probable TB) (n = 136) Bacteriologically confirmed TBa (n = 21) p-value
Median age in years at time of TB referral (IQR) 4.6 (1.5 – 9.1) 9.4 (4.5–12.1) 0.017
Male gender (%) 68 (50.0) 14 (66.7) 0.155
HIV positive (%) 73 (53.7) 11 (52.4) 0.912
Disposition at time of referral of “Inpatient” (%) 69 (50.7) 7 (33.3) 0.137
Past TB treatment (%) 5 (3.7) 2 (9.5) 0.237
Severe Malnutrition (%)b 42 (30.9) 8 (38.1) 0.509
Reported TB contact (%) 28 (20.6) 5 (23.8) 0.736
Diagnostic Tests Performed
 Sputum analysis (%) 94 (69.1) 21 (100.0) 0.001
 Chest x-ray (%) 91 (66.9) 16 (76.2) 0.460
 Tuberculin skin test (%) 123 (90.1) 20 (95.2) 0.695

  1. aBacteriologically confirmed TB is a TB case from whom a biological specimen is positive by smear microscopy, culture or Xpert MTB/RIF. bSevere acute malnutrition is defined as weight-for-height Z score <3 SD and/or presence of edema [29]
