Comparative analysis of non-tuberculous mycobacterial lung disease and lung colonization: a case-control study.
Article in BMC infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundNon-tuberculous mycobacteria (NTM) are common opportunistic pathogens, and the most common infection site is lung. NTM are found commonly in the environment. Many patients have NTM lung colonization (NTM-Col). NTM lung disease (NTM-LD) have no specific sympotms, though it is hard to differentiate NTM-LD and NTM-Col under this circumstance. The aim of this study is to explore the differences between NTM-LD and NTM-Col for future clinical diagnosis and treatment.
methodsWe retrospectively enrolled patients who had a history of NTM isolated from respiratory specimens in Peking Union Medical College Hospital (PUMCH) from January 1st, 2013 to December 31st, 2022. Patients were classified into NTM-LD group and NTM-Col group. Demographic characteristics, clinical manifestations, laboratory tests and imaging findings of the two groups were compared. Comparative analysis was also performed in peripheral blood lymphocyte subsets among three groups.
resultsA total of 127 NTM-LD patients and 37 NTM-Col patients were enrolled. Proportion of patients with bronchiectasis was higher in NTM-LD group than in NTM-Col group (P = 0.026). Predominant NTM isolates were Mycobacterium avium complex (MAC). NTM-LD group had a higher proportion of Mycobacterium intracellulare (P = 0.004). CD4
conclusionNTM isolates from both NTM-LD and NTM-Col patients were predominantly MAC, with a higher Mycobacterium intracellulare isolation rate in NTM-LD group. Imaging findings of bronchiectasis and lower peripheral blood CD4
