Significance of isolating non-tuberculous mycobacterial organisms in infertile women with tubal disease: an observational study.
Observational study in BJOG : an international journal of obstetrics and gynaecology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesTo explore whether non-tuberculous mycobacteria (NTM) are associated with tubal disease leading to infertility.
designProspective observational study.
settingTeaching hospital. POPULATION: Women with tubal factor infertility.
methodsIn all, 173 infertile women with tubal disease were investigated for genital tuberculosis, Chlamydia trachomatis and Neisseria gonorrhoeae using polymerase chain reaction, culture and histopathological examination. On culture, NTM were grown in 23.7% of endometrial samples. The mycolic characteristics of these organisms were analysed.
main outcome measureWhether NTM are associated with tubal disease leading to infertility.
resultsThe organisms identified in association with tubal disease were Mycobacterium tuberculosis in 30%, gonococci in 1.7%, Chlamydia in 7.5% and NTM in 23.7% of cases. Mycobacterium chelonae was the predominant organism identified by high-performance liquid chromatography. In ten women, for whom there was laparoscopic evidence of tubal disease, the only organism that was grown was NTM, and the tests for other organisms were negative. Tests for possible environment (theatre, instruments) contamination was reported negative.
conclusionWhile evaluating infertile women for tubal disease, culture studies revealed a high prevalence of NTM in the endometrium. In the absence of M. tuberculosis, gonococci and Chlamydia infection, the presence of NTM suggests the possibility that these organisms may be responsible for tubal damage leading to infertility. TWEETABLE ABSTRACT: On evaluating the causes of tubal disease, NTM were associated with tubal disease.
