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 Ganz approach and Kocher-Langenbeck (K-L) approach in Pipkin type IV femoral head fracture (FHF) with internal fixation.

methodsThe medical records of patients with Pipkin type IV FHF were assessed in the observational study. The patients were divided into Ganz approach group and K-L approach group. The surgical time, intraoperative blood loss, quality of acetabular fracture reduction, Thompson-Epstein clinical and radiological score, fracture healing time, Harris hip score, and complications were recorded.

resultsFifteen patients were followed for 12–23 months (mean 16.8 months). The Ganz approach group showed significantly better Thompson-Epstein clinical and radiological scores (7 excellent, 1 good) than the K-L group (2 excellent, 5 good) (P < 0.05). According to Matta radiographic criteria, anatomical reduction was achieved in 6 cases (with 2 satisfactory) in the Ganz group compared to 5 cases (with 2 satisfactory) in the K-L group, demonstrating a non-significant trend toward superiority for the Ganz approach (P > 0.05).

conclusionCompared with the traditional K-L approach, the Ganz approach offers better visual field exposure, better reduction quality of FH, and better postoperative functional recovery.
