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
objectiveThis study aimed to assess the diagnostic value of the sagittal and transverse views of the suprapubic window during a Focused Assessment with Sonography in Trauma (FAST) or extended FAST (eFAST) examination.
methodsThis retrospective chart review analyzed suprapubic windows of FAST/eFAST images performed from August 15, 2017, to August 1, 2024. Each ultrasound video was reviewed for the presence or absence of free fluid, image quality, and diagnostic confidence. Reviewers were blinded to clinical information and did not assess more than one imaging plane in the same patient.
resultsOf the 958 FAST/eFAST studies identified, 497 met inclusion criteria. Of these, 433 (87.1%) were diagnostic, while 64 (12.9%) were nondiagnostic in at least one imaging plane. Among diagnostic images, 93 (21.5%) sagittal views and 74 (17.1%) transverse views were positive for free fluid. A total of 32 exams (34.4%) showed free fluid in the sagittal views but were negative on the transverse view, whereas 13 cases (17.6%) were positive on the transverse view but negative on the sagittal view. Using both views reduced overall nondiagnostic rate from 12.9% to 1.2%.
conclusionUsing both sagittal and transverse views in the suprapubic window during a FAST/ eFAST examination can reduce the nondiagnostic rates and improve identification of free fluid. The observed discrepancies between views and variability in the image quality and confidence support a multiview approach.
