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

Objectives: To compare the measurement reliability, procedural efficiency, and infant stress responses between device-assisted and manual restraint approaches in Graf hip ultrasonography for developmental dysplasia of the hip (DDH) screening. Methods: In this retrospective cohort study, 238 infants (aged 0-6 months) underwent consecutive hip ultrasound examinations using both a Graf stabilization device and manual restraint during the same visit. Each examination included triple measurements of Results: No significant differences were observed in Conclusion: The use of a stabilization device in Graf hip ultrasonography significantly improves measurement reliability and may enhance examination efficiency and infant comfort without altering diagnostic outcomes, supporting its integration into high-volume DDH screening programs.
