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
Outcomes in acute limb ischemia (ALI) depend on early recognition. Rapid evaluation methods in the emergency department (ED) include physical exam, hand-held Doppler (HH), or spectral Doppler (SD) using point-of-care ultrasound (POCUS). This study aims to estimate performance characteristics of HH versus emergency medicine (EM)-performed SD compared to angiography along with clinician confidence when evaluating for ALI. This was a prospective observational pilot study. A convenience sample of patients presenting to an urban, academic ED with concern for ALI who underwent angiography were eligible. The primary aim evaluated diagnostic performance of HH and SD in correctly classifying flow in posterior tibial (PT) and dorsalis pedis (DP) arteries in patients with 100% angiographic occlusion of the proximal vasculature. Binomial exact 95% confidence intervals (CIs) and Fisher's exact tests were used. Twenty-six patients were enrolled. Three cases (11.5% of 26) had normal angiography, five (19.2%) had partial occlusion, and 18 (69.2%) had 100% occlusion. For cases with 100% occlusion, HH always classified PT or DP as abnormal (sensitivity 100, 95% CI 81.5-100%). SD also showed high sensitivity (94.4, 95% CI 72.7-99.9%). Limited utility of specificity calculations was due to low true negatives (n = 3), but these measures were low for HH (66.7, 95% CI 9.4-99.2%) and SD (33.3, 95% CI 0.8-90.6%). There was no association (p = .305) between sonographer confidence and correct diagnostic classification for either HH or SD. In a patient population with suspected ALI, EM-performed HH and SD performed extremely well at identifying abnormal PT or DP flow in patients with complete (100%) angiographic occlusion. These results are useful to power larger trials to determine the role that SD may play in complementing HH evaluation for ALI.
