Collagen-V and K-α-1 Tubulin Antibodies as Potential Markers of Unsuspected GERD-Related Lung Damage: Insights from a Cross-Sectional Analysis.

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
purposeOur group has proposed that aspiration of gastric contents leads to exposure of normally sequestered lung self-antigens (SAgs), specifically collagen-V (Col-V) and K-α-1-tubulin (Kα1T), which elicits an immune response characterized by increasing concentrations of self-antibodies (SAbs) anti-Col-V and anti-Kα1T. We sought to establish the point prevalence of abnormally elevated concentrations of SAbs among patients with pathological gastroesophageal reflux disease (GERD) and/or hiatal hernia undergoing antireflux surgery (ARS).
methodsFor this cross-sectional study, we retrieved a plasma aliquot from the Norton Thoracic Institute BioBank from blood samples that were taken preoperatively from patients who underwent ARS between November 2019 and August 2022. Enzyme-linked immunosorbent assays were employed to detect and quantify anti-Col-V and anti-Kα1T.
resultsSamples from 43 patients (females, n = 34 [79.1%]; mean age, 62 ± 12 years; and mean BMI, 30.5 ± 7 kg/m
conclusionA relative high point prevalence of abnormally elevated circulating SAbs (i.e., anti-Col-V and/or anti-Kα1T) before ARS was found. This result suggests clinically unsuspected pulmonary parenchymal injury secondary to GERD-related aspiration. Further studies are required to confirm this hypothesis and to identify alternative non-invasive early biomarkers of GERD-related lung damage.
