Incidence of relapses among patients treated with antibiotics and chemotherapy.

Two groups of 1,000 patients each are included in this evaluation. The first thousand belong to the dispensary and include people from the lower social and economical levels. Those having better means, able to pay their medical care, are included in the second thousand. Half of the patients in the dispensary were treated during the early antituberculosis drug era, and the other 50 per cent were treated after these drugs were readily available and adequate dosage was given. Also the group from private practice was divided in the same proportion. The patients belonging to the early era were all treated according to our directions. The second group coming to us, as a rule, had already received treatment by their doctors or even self prescribed. We have separated the group of children from that of adults and tried to show when treatment was insufficient, poorly indicated, early abandoned, or started too soon. Results:
