Table 1 Patient Characteristics: Median ages and CD4 counts, rates of TB positivity, and associated mortality of all TB+ patients that submitted sputum for comparison, stratified by hospitalized and ambulatory groups

From: Evaluation of Microscopic Observation Drug Susceptibility (MODS) and the string test for rapid diagnosis of pulmonary tuberculosis in HIV/AIDS patients in Bolivia

  n Median Age (IQR) Median CD4 count (IQR) TB+ (%) Mortality of TB+
All patients 107 32 (27–43) 98 (33–249) 48/107 (44.9 %) 22/48 (45.8 %)
Hospitalized patients 76 32 (27–46)* 76.5 (29.0-162)** 35/76 (46.1 %)*** 18/35 (51.4 %)****
Ambulatory patients 31 32 (28–42)* 192 (64–339)** 13/31 (41.9 %)*** 4/13 (30.7 %)****
  1. 107 patients were included in analysis. Median age of all patients as well as those hospitalized vs ambulatory was 32. Median CD4 count for all patients was 98. Median CD4 count of hospitalized patients was 76 and median CD4 for ambulatory patients was 192. Rates of TB positivity (TB+), defined as a patient with a sputum or gastric string sample that was culture positive by MODS or Lowenstein Jensen, was 44.9 % in all patients, 46.1 % in hospitalized patients, and 41.9 % in ambulatory patients. Of those who were TB+, the mortality rate overall was 45.8 %. The mortality rate for hospitalized TB+ patients was 51.4 % and for ambulatory TB+ patients, it was 30.7 %
  2. n number of patients in each group. Medians are displayed in year. IQR Interquartile range
  3. *The difference between the median age of hospitalized versus ambulatory patients was not statistically significant (p = 0.87)
  4. **The difference between the median CD4 count of hospitalized versus ambulatory (76.5 vs 192) was statistically significant (p = 0.01)
  5. **The difference between the rates of TB of hospitalized vs ambulatory patients (46.1 % vs 41.9 %) was not statistically significant (p = 0.70)
  6. ***The difference between the mortality of the TB+ hospitalized patients vs mortality of TB+ ambulatory patients (51.4 % vs 30.7 %) was not statistically significant (p = 0.08)
