Fig 1. Circulating levels of ferritin, but not CRP, substantially decrease in pulmonary TB patients undergoing anti-tuberculous therapy (ATT).

Fig 1

(A) Serum concentrations of ferritin and CRP were prospectively measured in a cohort of 165 treatment-naïve patients with culture confirmed pulmonary TB. Lines and whiskers represent median and interquartile values. Data were analyzed using Kruskal Wallis test with Dunn’s multiple comparisons. Statistically significant differences are highlighted. *P<0.05; **P<0.01. (B) Serum levels of Ferritin and CRP were tested for correlations at different study time points. Data were analyzed using the Spearman’s rank test. Non-linear curve fit analysis was used to illustrate the trends in data distribution in the correlation plots. (C) Concentrations of ferritin and CRP were examined prospectively in patients stratified by HIV infection status.
