P values by χ2 tests were used to compare categorical variables between individuals with definite active TB and individuals without active TB. A P value of <0.025 was considered statistically significant.
P values by χ2 tests were used to compare categorical variables between individuals with suspected active TB and individuals without active TB. A P value of <0.025 was considered statistically significant.

Self-reported history of TB who had been diagnosed before 2016.
BMI, body mass index; IQR, interquartile range; TB, tuberculosis. The sum might not equal the total because of missing data.
