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

backgroundStudies suggest that statins and angiotensin-converting enzyme (ACE) inhibitors might be beneficial for the treatment of infections. Our purpose was to examine the association of statin, ACE inhibitor, and angiotensin II receptor blocker (ARB) use with pneumonia-related outcomes.

methodsWe conducted a retrospective cohort study using Department of Veterans Affairs data of patients aged ≥ 65 years hospitalized with pneumonia. We performed propensity-score matching for 3 medication classes simultaneously.

resultsOf 50119 potentially eligible patients, we matched 11498 cases with 11498 controls. Mortality at 30 days was 13%; 34% used statins, 30% ACE inhibitors, and 4% ARBs. In adjusted models, prior statin use was associated with decreased mortality (odds ratio [OR], 0.74; 95% confidence interval [CI], .68-.82) and mechanical ventilation (OR, 0.81; 95% CI, .70-.94), and inpatient use with decreased mortality (OR, 0.68; 95% CI, .59-.78) and mechanical ventilation (OR, 0.68; 95% CI, .60-.90). Prior (OR, 0.88; 95% CI, .80-.97) and inpatient (OR, 0.58; 95% CI, .48-.69) ACE inhibitor use was associated with decreased mortality. Prior (OR, 0.73; 95% CI, .58-.92) and inpatient ARB use (OR, 0.47; 95% CI, .30-.72) was only associated with decreased mortality. Use of all 3 medications was associated with reduced length of stay.

conclusionsStatins, and to a lesser extent ACE inhibitors and ARBs, are associated with improved pneumonia-related outcomes. Prospective cohort and randomized controlled trials are needed to examine potential mechanisms of action and whether acute initiation at the time of presentation with these infections is beneficial.
