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

The aim of this study was to investigate whether inhaled corticosteroid (ICS) use affects outcome in patients with chronic obstructive pulmonary disease (COPD) admitted with community-acquired pneumonia (CAP). This was a prospective, observational study of patients with spirometry-confirmed COPD presenting with a primary diagnosis of CAP in Lothian, UK. Outcome measures were compared between ICS users and non-ICS users. Of 490 patients included in the study, 76.7% were classified as ICS users. ICS users had higher Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage compared with non-ICS users (mean ± sd 3.2 ± 0.8 versus 2.6 ± 0.9; p<0.0001). There were no significant differences in pneumonia severity (mean ± sd Pneumonia Severity Index (PSI) 4.2 ± 0.8 versus 4.3 ± 0.8 (p = 0.3); mean ± sd CURB-65 score 2.1 ± 1.3 versus 2.3 ± 1.3 (p = 0.07)) or markers of systemic inflammation (median C-reactive protein 148 (interquartile range 58-268) mg·L(-1) versus 183 (IQR 85-302) mg·L(-1); p = 0.08) between ICS users and non-ICS users. On multivariable analysis, after adjustment for COPD severity and PSI, ICS use was not independently associated with 30-day mortality (OR 1.71, 95% CI 0.75-3.90; p = 0.2), 6-month mortality (OR 1.62, 95% CI 0.82-3.16; p = 0.2), requirement for mechanical ventilation and/or inotropic support (OR 0.73, 95% CI 0.33-1.62; p = 0.4) or development of complicated pneumonia (OR 0.71, 95% CI 0.25-1.99; p = 0.5). Prior ICS use had no impact on outcome in patients with COPD admitted with CAP.
