Culture conversion and drug susceptibility in drug-resistant pulmonary tuberculosis with type 2 diabetes mellitus on oral regimens.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe simultaneous existence of multidrug-resistant pulmonary tuberculosis (MDR-PTB) and type 2 diabetes mellitus (T2DM) represents a rising threat in high-burden countries such as India. Diabetes has been associated with impaired immune responses and delayed bacteriological clearance, thereby compromising treatment outcomes in patients with multidrug-resistant tuberculosis receiving all-oral longer regimens.
aimImpact of T2DM on clinical profile, radiological severity, drug resistance patterns, and sputum culture conversion in MDR-PTB.
methodsThis prospective observational study included 264 adults with microbiologically confirmed MDR-PTB treated at a tertiary care center in North India over a 12-month period. The participants were classified as diabetic, pre-diabetic, or non-diabetic according to the American Diabetes Association 2023 criteria. Clinical, radiological, microbiological, and drug susceptibility data were analyzed. Time to culture conversion and treatment outcomes were compared across groups using appropriate statistical tests.
resultsPatients with diabetes were older and had higher rates of dyspnea and hemoptysis. Radiologically, they demonstrated significantly higher rates of bilateral lung involvement and lower zone involvement. A higher bacillary load and increased prevalence of
conclusionT2DM adversely affects bacteriological response, radiological severity, and treatment outcomes in patients with MDR-PTB on all-oral longer regimens.
