Chi-square test; a value is for the difference between the two groups, i.e., the antimicrobial modified group and the no-change group. Seven patients (4.7%) were human immune deficiency virus positive (HIV-positive). The most common symptom at presentation was cough in 107 patients (71.33%) followed by breathlessness in 97 patients (64.66%). Other symptoms included sputum production (n = 72 (48%)), fever (n = 71 (47.33%)), and haemoptysis (n = 4 (2.67%)).
