Nontuberculous Mycobacterial Lung Disease Management in Belgium: A Longitudinal Pharmacy Database Study.
Article in Drugs - real world outcomes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectiveNontuberculous mycobacteria (NTM) are opportunistic pathogens that can cause lung disease (NTMLD) in susceptible individuals, but NTMLD management is challenging. This study aims to describe real-world NTMLD treatment patterns in Belgium.
methodsThis retrospective study used data from the IQVIA longitudinal pharmacy database. Patients with presumed NTMLD (i.e., who initiated prespecified NTM treatments from October 2015 through September 2019) were included. Variables of interest were initiated prescribed regimens, medication possession rate (MPR), and treatment persistence, switches, and restarts.
resultsOverall, 199 presumed NTMLD patients initiated 72 triple- and 130 dual-drug regimens. The average triple-drug therapy MPR was 88%, and median treatment duration was 225 days. Sixty percent and 30% of patients remained on initial therapy at 6 and 12 months, respectively. Therapy switches were common, with up to five switches per patient. Seventeen percent of initiated therapies were stopped for more than 60 days but restarted within 1 year.
conclusionDespite inherent methodological limitations, results indicate therapy switches, premature treatment interruption, and restarting multidrug oral NTM treatment are common. These findings underscore the need for improved management of NTMLD through enhanced monitoring as well as more tolerable and effective treatment options.
