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

introductionInterleukin-1 beta (IL-1beta) and tumor necrosis factor alpha (TNFalpha) are potentially important in Chronic Obstructive Pulmonary Disease (COPD), but little is known of the relationships between these cytokines and their antagonists in disease compared with healthy controls. It is unclear if concentrations relate to disease severity. The study aimed to investigate these relationships and to assess the potential activity of each cytokine in the context of their antagonists.

methodsPlasma cytokines, soluble receptors, and cell counts were measured in patients with stable COPD and age-matched healthy controls (n = 15 for both) daily for 5 days; these mediators were also measured in corresponding sputum samples from the COPD patients.

resultsCOPD patients had significantly reduced concentrations of the antagonists, IL-1sRII, and IL-1RA compared with controls. In COPD, IL-1beta exceeded its antagonists and correlated significantly with BMI and FEV1, while plasma IL-1RA correlated positively with BMI but negatively with sputum IL-1beta, neutrophil, and macrophage counts and smoking history. TNFalpha antagonists exceeded agonists in both groups and did not correlate with COPD severity.

conclusionsEndogenous IL-1beta antagonists appear reduced in COPD. Furthermore, IL-1beta correlated with clinical aspects of disease severity, suggesting that IL-1beta may play a critical role in COPD. Given the relevant concentrations and binding affinities, it is likely that TNFalpha has limited activity in stable COPD.
