COPD – Chronic obstructive pulmonary disease; TB – Tuberculosis; n – number of participants with COPD, pneumonia or TB within each score; % – Percentage of participants with COPD, pneumonia or TB within each score; df – Degrees of freedom, P<0.05 – Statistically significant. Chi-square value 15 at eight degrees of freedom. χ2 – Chi-square test value; P – Statistical significance
