Prevalence, Distribution, and Risk Factors of Mycobacterium Other Than Tuberculosis Among Tuberculosis Presumptive Patients in Karonga District in Malawi.

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
introductionBesides tuberculosis (TB), there are also other nontuberculous mycobacteria (NTM) that present with similar clinical signs and symptoms as TB. If not promptly found and treated, these organisms may affect the programming of the TB control and elimination campaign. The study sought to establish the prevalence, distribution, and factors contributing to MOTT infections among presumptive TB patients in the Karonga district.
methodsA descriptive cross-sectional study research design was employed. A total of 196 participants were included in the study using a census approach. Data were collected by administering a questionnaire to the health care worker, and a sputum specimen was collected from the participants; this specimen was used to examine the presence of mycobacterium using the microscope. Regardless of the results at the district-level laboratory, all the specimens were then sent to the Mzuzu region TB reference laboratory to isolate Mycobacterium tuberculosis and Mycobacterium Other Than Tuberculosis.
resultsOf the 196 samples collected, 14 (7.1%) were positive at the district level. When sent for culture, 195 (99.5%) had culture results, and 23 (12%) had growth in culture. Out of the 23 (100%) culture-positive results, 12 (52%) were MOTT-positive, while 11 (48%) were MTB complex. There were more men, seven (58%) with MOTT-positive than women, five (42%), and more in the age group of 15-39 years old, with six (50%) and less in more than 60 years old two (16.7%).
conclusionThe results show the presence of MOTT infections among presumptive TB patients who submitted samples to the study. The distribution by sex shows that more men had MOTT infections than women. However, all the risk factors listed for the study were not significant for MOTT infections. The recommendation is to improve the testing techniques to identify these microorganisms, which are neglected but very difficult to assess, especially when no clear population is at risk of getting these infections compared with TB.
