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

backgroundOxidative stress is a key element in the pathogenesis of emphysema, but oxidation of nucleic acids has been largely overlooked. The aim of this study was to investigate oxidative damage to nucleic acids in severe emphysematous lungs.

methodsThirteen human severe emphysematous lungs, including five with alpha(1)-antitrypsin deficiency (AATD), were obtained from patients receiving lung transplantation. Control lung tissue was obtained from non-COPD lungs (n = 8) and donor lungs (n = 8). DNA and RNA oxidation were investigated by immunochemistry. Morphometry (mean linear intercept [Lm] and CT scan) and immunostaining for CD68 and neutrophil elastase also were performed.

resultsNucleic acid oxidation was increased in alveolar wall cells in emphysematous lungs compared to non-COPD and donor lungs (p < 0.01). In emphysematous lungs, oxidative damage to nucleic acids in alveolar wall cells was increased in the more severe emphysematous areas assessed by histology (Lm, > 0.5 mm; p < 0.05) and CT scan (< -950 Hounsfield units; p < 0.05). Compared to classic emphysema, AATD lungs exhibited higher levels of nucleic acid oxidation in macrophages (p < 0.05) and airway epithelial cells (p < 0.01). Pretreatments with DNase and RNase demonstrated that RNA oxidation was more prevalent than DNA oxidation in alveolar wall cells.

conclusionsWe demonstrated for the first time that nucleic acids, especially RNA, are oxidized in human emphysematous lungs. The correlation between the levels of oxidative damage to nucleic acids in alveolar wall cells and the severity of emphysema suggest a potential role in the pathogenesis of emphysema.
