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

backgroundKrackow suturing and suture bridge technique was compared with Kirschner-Wire (K-wire) tension band and patella cerclage for the fixation of inferior pole patella fracture.

methodsThis was a retrospective study of 47 patients with inferior pole patella fractures who underwent fixation procedures at our hospital between January 2019 and May 2022, of whom 25 had Krackow suturing combined with the suture-bridge technique (GROUP 1), and 22 received a K-wire tension band combined with patellar cerclage (GROUP 2). We compared the operative time, reoperation rate, Böstman score, knee range of motion (ROM), fracture-healing time, Insall-Salvati index, complications and hospital expenses between the two groups.

resultsThe average follow-up period was 23.1 ± 5.8 months. The complication and reoperation rates in the GROUP 2 were significantly higher than those in the GROUP 1 (P = 0.023 and P < 0.001). While the GROUP 1 has lower hospital expenses than GROUP 2 (P < 0.001). However, significant differences were not found regarding the Böstman score, knee ROM, Insall-Salvati index, fracture-healing time, and operation time between the two groups.

conclusionsBoth Krackow suturing combined with the suture-bridge technique and the K-wire tension band technique can achieve comparable clinical efficacy in stably fixing inferior patellar pole fractures, subsequently allowing an early commencement of rehabilitation exercise, while the suture-bridge technique can also reduce the incidence of complications, hospital expenses and the need for reoperation surgery.
