Diagnostic accuracy of pocket-sized ultrasound for aspiration pneumonia in elderly patients without heart failure: A prospective observational study.
Observational study in Geriatrics & gerontology international, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
aimTo investigate the diagnostic accuracy of pocket-sized ultrasound (PsUS) for aspiration pneumonia in elderly patients without heart failure.
methodsThis prospective observational study included patients with aspiration pneumonia. PsUS was performed in six areas (bilateral chest, four dorsal areas) by an independent examiner, blinded to the computed tomography (CT) results as a reference standard. Patients with heart failure were excluded.
resultsPsUS findings of 34 patients (median age, 87.5 years) and 204 areas were analyzed. Three or more B-lines (comet tail artifacts) were strongly suggestive (positive likelihood ratio [LR+] 17.302) of consolidation on CT (CT-consolidation, subpleural hypoechoic area with tissue-like echostructure) or pleural change on CT. Consolidation on US (US-consolidation) was suggestive of CT-consolidation or pleural changes on CT (LR+ 6.453). Pleural effusion on US was strongly suggestive (LR+ 10.989) of CT-consolidation or pleural change on CT. Absence of either three or more B-lines, US-consolidation, or US pleural effusion could not rule out CT-consolidation or pleural change on CT (negative likelihood ratio [LR-] 0.482-0.683). However, absence of all three findings could rule out abnormal CT findings (LR- 0.230). Chest radiograph findings proved difficult to confirm or exclude CT-consolidation or pleural changes on CT (LR+ 1.584, LR- 0.489); when combined with PsUS findings, LR- improved to 0.124.
conclusionsThree or more B-lines or US-consolidation on PsUS in elderly patients with aspiration pneumonia without heart failure suggested CT-consolidation or pleural changes on CT. When both PsUS and chest radiograph findings were negative, CT-consolidation and pleural change could be excluded. Geriatr Gerontol Int 2021; 21: 1118-1124.
