Assessment of macrolide resistance in the respiratory tract of preterm-born infants during treatment with azithromycin in the AZTEC clinical trial.
Trial report in Thorax, 2026. 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
backgroundOur multicentre, double-blind, randomised, placebo-controlled Azithromycin therapy for prevention of chronic lung disease of prematurity trial assessed if early 10-day azithromycin treatment improved survival without development of chronic lung disease of prematurity when compared with placebo in 796 preterm-born infants. Since antibiotic resistance remains a significant global health priority, we had preplanned macrolide-resistance assessment in recruited infants. We, therefore, identified baseline macrolide-resistant genes in respiratory samples and determined if this was altered by azithromycin treatment. Furthermore, we assessed if macrolide-resistant bacteria isolated from respiratory samples were also resistant to other common antibiotic classes.
methodsSix common macrolide-resistant genes:
resultsFrom 1108 (n=541 azithromycin, n=567 placebo) respiratory aspirates from 348 preterm infants, the overall prevalence of macrolide-resistant genes was similar in the placebo (63.7%) and azithromycin (63.9%) groups, with only
conclusionsMacrolide-resistant genes were noticeably prevalent in the placebo group, with minimal increase with azithromycin treatment, suggesting that, regardless of the additional use of azithromycin, judicious use of antibiotics is required in preterm-born infants.
