Categorical variables are expressed as frequencies (n) and percentages (%), and quantitative variables are expressed as median and interquartile ranges (IQR) or standard deviation (SD). Statistical differences between pairwise comparisons (a). QFT-GIT, QuantiFERON-TB Gold In-Tube; TB, tuberculosis; LTBI, latent tuberculosis infection; Z-score, default classification system used to present child nutritional status; BCG, Bacillus Calmette-Guérin. Bold values, statistical significative values with a p-value under 0.05.
