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

Point-of-care ultrasound (PoCUS) has emerged as a critical tool for diagnosing intrauterine pregnancy (IUP) in symptomatic first-trimester patients, particularly in emergency settings. This meta-analysis aims to evaluate the test characteristics of PoCUS in diagnosing IUP. As a secondary objective, this study will also examine the accuracy of PoCUS in detecting fetal cardiac activity (FCA). This systematic review and meta-analysis was conducted following the PRISMA-DTA guidelines with the protocol registered in PROSPERO (ID: CRD42024596206). We performed a comprehensive search of PubMed, Scopus, Web of Science, Cochrane Library and Google Scholar up to November 2024, identifying studies that compared PoCUS to reference standards for IUP diagnosis. Seven studies (n = 1716) were included in the meta-analysis. Two independent reviewers performed study selection, data extraction, and quality assessment using the QUADAS-2 tool. A bivariate random-effects model was used to pool the diagnostic accuracy metrics. In this meta-analysis, PoCUS demonstrated a pooled sensitivity of 86.3% (95% CI: 75.6%-92.8%, I
