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

objectiveThis study was designed to investigate the sensitivity and specificity of the three-dimensional (3D) pelvic floor ultrasound and the conventional ultrasound in pelvic floor assessment after delivery.

methodsA total of 108 patients with pelvic floor dysfunction treated in our hospital were selected as the study group, and another 108 healthy subjects were included as the control group. Both groups were diagnosed by conventional ultrasound and 3D pelvic floor ultrasound, and confirmed with pathological findings. The diagnostic results of the conventional ultrasound and 3D pelvic floor ultrasound were compared, and the diagnostic conditions of various indicators in the two groups were compared.

resultsThe numbers of true positive cases and true negative cases diagnosed by the conventional ultrasound were 84 and 90, respectively, while the numbers of true positive cases and true negative cases diagnosed by the 3D pelvic floor ultrasound were 8 and 102, respectively (

conclusionThe 3D pelvic floor ultrasound is more accurate, specific and sensitive than the conventional ultrasound in the assessment of postpartum pelvic floor function, which is worthy of wide application.
