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

ObjectiveTo compare the efficacy of robot-assisted versus traditional core decompression combined with human umbilical cord-derived mesenchymal stem cell transplantation for osteonecrosis of the femoral head.MethodsA total of thirty-eight patients were divided into two groups according to the surgical technique. The observation group (20 patients, 28 hips) underwent robot-assisted core decompression, while the control group (18 patients, 22 hips) underwent traditional decompression. Both groups underwent human umbilical cord-derived mesenchymal stem cell implantation. Relevant parameters were compared between the groups.ResultsAt the final follow-up, the observation group showed lower visual analog scale scores and necrotic volume as well as higher Harris hip scores and femoral head survival rates than the control group; however, these differences were not statistically significant. The observation group required significantly fewer intraoperative fluoroscopies, experienced less intraoperative blood loss, and had a shorter operation time than the control group (all
