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

backgroundDevelopment of bronchiolitis obliterans syndrome (BOS) after lung transplantation confers increased patient morbidity and mortality. Fibrocytes are circulating bone marrow-derived mesenchymal cell progenitors that influence tissue repair and fibrosis. Fibrocytes have been implicated in chronic pulmonary inflammatory processes. We investigated the correlation of circulating fibrocyte number with BOS development in lung transplant patients.

methodsWe prospectively quantified circulating fibrocyte levels among lung transplant patients. Patients were stratified according to the development of BOS as indicated by predicted forced expiratory volume in 1 second. Fibrocyte activity was analyzed by flow cytometry (cluster of differentiation 45+, collagen 1+) in a blinded manner related to clinical presentation.

resultsThirty-nine patients (61.5% men) underwent double (33.3%), left (25.6%), or right (41.0%) lung transplantation. Average patient age was similar between BOS and non-BOS patients (58.3±3.9 vs 60.3±2.0 years, p=0.67). Chronic obstructive lung disease was the most common indication for lung transplantation (41.0%). Median forced expiratory volume in 1 second was lower among BOS patients compared with non-BOS patients (1.08 vs. 2.18 L/s, p=0.001). Importantly, circulating fibrocyte numbers were increased in BOS patients compared with non-BOS patients (8.91 vs 2.96×10(5) cells/mL, p=0.03) by flow cytometry and were incrementally increased with advancing BOS stage (p=0.02).

conclusionsIncreased circulating fibrocyte levels correlate with the development of BOS after lung transplantation and positively correlate with advancing BOS stage. Quantification of circulating fibrocytes could serve as a novel biomarker and possible therapeutic target for BOS development in lung transplant patients.
