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

backgroundPatients with nontuberculous mycobacterial (NTM) diseases associated with anti-interferon gamma autoantibodies (anti-IFN-γ auto-Abs) often experience recurrences, despite prolonged treatment, which requires intravenous anti-mycobacterial therapy. Linezolid (LZD) shows a potential as an adjunct treatment, but there is limited data on its long-term efficacy and safety.

methodsWe conducted a prospective study from December 2017 to April 2022, to evaluate the efficacy of a nine-month oral LZD regimen in reducing NTM treatment failure, defined as relapse and the need for intravenous anti-mycobacterial therapy for suspected uncontrolled NTM or death as well as to determine its tolerability.

resultsAmong 40 adults (≥18 years) with NTM diseases and anti-IFN-γ auto-Abs treated with linezolid, 10 (25%) discontinued treatment early due to adverse events (AEs), including one death from suspected uncontrolled diseases at month seven. Of the 30 patients who completed the nine-month course, only five maintained their initial dose. The remaining 25 required dose modification: four temporarily paused treatment due to AEs, nine reduced to a half dose due to AEs, and 12 reduced their dose because of stable disease. By month nine, the cumulative incidence rates of relapse and treatment failure were 22.5 and 15.0%, respectively; consequently, 77.5% and 85.0% of patients remained free from the relapse and treatment failure. Overall, 24 patients (60%) reported a total of 31 AEs, with anemia and peripheral neuropathy being the most frequent.

conclusionOur findings suggest that linezolid could be a valuable adjunct treatment for nontuberculous mycobacteria diseases in patients with anti-interferon gamma autoantibodies. However, close monitoring for adverse events is essential.
