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

In patients with developmental dysplasia of the hip (DDH), complications such as head dislocation and cup instability after total hip arthroplasty (THA) are often caused by poor cup positioning. However, no planning algorithm currently considers both the cup bony coverage rate (BCR) and the hip impingement-free range of motion (IFROM) simultaneously due to the high variability in cup position and the difficulty in parameterizing IFROM after THA. This study proposed an algorithm to efficiently calculate the BCR and IFROM for all potential cup positions, filtering out the cup's optimal implant position. The IFROM evaluation coefficients (EC
