The patients were treated using the WHO standard 6-month regimen that included 2 months of isoniazid/rifampicin/pyrazinamide/ethambutol and 4 months of isoniazid/rifampicin (2HRZE/4HR). The directly observed therapy (DOT) strategy was followed in the intensive phase of treatment, while community volunteers were involved in monitoring the patients in the continuous phase. During the initial and follow-up visits, the patients were told to report any symptoms they developed that may indicate the relapse of the disease to their TB unit.
