1 · What the graph read from it

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.

2 · The registry

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

backgroundLongitudinal studies comprehensively evaluating the direction of the relationship between chronic obstructive pulmonary disease (COPD) and non-tuberculous mycobacterial pulmonary disease (NTM-PD) are scarce. Therefore, this study aimed to evaluate whether COPD influences the development of NTM-PD even after considering various confounders by using a nationwide longitudinal cohort study.

methodsData from the National Health Insurance Service National Sample Cohort between 2002 and 2019 were analysed. Participants≥20 years of age with COPD and no previous NTM diagnosis were included in the study. The incidence of NTM-PD was compared between participants with COPD (n=8939) and 1:4 fully matched control participants (n=32 355). Participants were followed until the date of NTM-PD incidence, death, or December 2019.

resultsDuring a median follow-up of 9.0 years (IQR, 5.0-12.9 years), participants with COPD (55.5 per 100 000 person-years) had a higher incidence of NTM-PD than matched control cohorts (25.4 per 100 000 person-years), with a HR of 2.16 (95% CI, 1.45 to 3.23). Age, sex, smoking history, asthma, bronchiectasis and corticosteroid use did not affect the association between COPD and the risk of incident NTM-PD (

conclusionsIndividuals with COPD had approximately a twofold increased risk of developing NTM-PD compared with matched controls. Being underweight and having bronchiectasis were identified as risk factors for developing NTM-PD.
