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.

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.

Despite its importance, there is limited evidence to guide management, particularly the use of disimpaction devices.

methodsLIFT is a prospective observational trial comparing the use of two commercially available disimpaction devices-the Fetal Pillow DISCUSSION: The LIFT study will compare the performance of the Fetal Pillow
