COPD – Chronic obstructive pulmonary disease; TB – Tuberculosis; n – Number of participants with COPD, pneumonia or TB within each category; % – Percentage of participants with COPD, pneumonia or TB within each category; df – Degrees of freedom, P<0.05 – Statistically significant. Chi-square value 7 at four degrees of freedom.χ2 – Chi-square test value; P – Statistical significance
