Clinical outcomes in patients with COPD hospitalized with SARS-CoV-2 versus non- SARS-CoV-2 community-acquired pneumonia.
Observational study in Respiratory medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
backgroundPatients with chronic obstructive pulmonary disease (COPD) have poor outcomes in the setting of community-acquired pneumonia (CAP) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The primary objective is to compare outcomes of SARS-CoV-2 CAP and non-SARS-CoV-2 CAP in patients with COPD. The secondary objective is to compare outcomes of SARS-CoV-2 CAP with and without COPD.
methodsIn this analysis of two observational studies, three cohorts were analyzed: (1) patients with COPD and SARS-CoV-2 CAP; (2) patients with COPD and non-SARS-CoV-2 CAP; and (3) patients with SARS-CoV-2 CAP without COPD. Outcomes included length of stay, ICU admission, cardiac events, and in-hospital mortality.
resultsNinety-six patients with COPD and SARS-CoV-2 CAP were compared to 1129 patients with COPD and non-SARS-CoV-2 CAP. 536 patients without COPD and SARS-CoV-2 CAP were analyzed for the secondary objective. Patients with COPD and SARS-CoV-2 CAP had longer hospital stay (15 vs 5 days, p < 0.001), 4.98 higher odds of cardiac events (95% CI: 3.74-6.69), and 7.31 higher odds of death (95% CI: 5.36-10.12) in comparison to patients with COPD and non-SARS-CoV-2 CAP. In patients with SARS-CoV-2 CAP, presence of COPD was associated with 1.74 (95% CI: 1.39-2.19) higher odds of ICU admission and 1.47 (95% CI: 1.05-2.05) higher odds of death.
conclusionIn patients with COPD and CAP, presence of SARS-CoV-2 as an etiologic agent is associated with more cardiovascular events, longer hospital stay, and seven-fold increase in mortality. In patients with SARS-CoV-2 CAP, presence of COPD is associated with 1.5-fold increase in mortality.
