Smear positive tuberculosis and genetic diversity of M. tuberculosis isolates in individuals visiting health facilities in South Gondar Zone, northwest Ethiopia.
Article in PloS one, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundTuberculosis (TB), a bacterial infectious disease, continues to be a public health concern in many developing countries. However, lack of data concerning the public health burden and potential risk factors for the disease hampers control programs in target areas. Therefore, the aims of present study were to determine the prevalence of TB and genetic diversity of M. tuberculosis isolates from individuals visiting health facilities in South Gondar Zone, northwest Ethiopia.
methodsA cross-sectonal study was conducted between March 2015 and April 2017. Bacteriological examination, region of difference (RD) 9 based polymerase chain reaction (PCR) and spoligotyping were used.
resultsThe overall prevalence of all smear positive TB was 6.3% (186/2953). Extra pulmonary TB (EPTB) was clinically characterized in about 62.4% (116/186) TB-positive cases. Some demographic characteristics, such as patients' origin (districts where patients were recruited) [patients' origin (chi-square (χ2) value; 62.8,p<0.001) were found to be significantly associated risk factors for the occurrence of TB in the study area. All the mycobacterial isolates were found to be M. tuberculosis. Among the 35 different spoligotype patterns identified, 22 patterns were shared types.The three dominantly identified families were T, CAS and Manu, each consisting of 46.9%, 24.0% and 10.4% of the isolates, respectively.
conclusionThe present study revealed that TB continues to be a public health problem in South Gondar Zone which suggests a need of implementing effective disease control strategies.
