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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSurgical treatment of Seinsheimer type V subtrochanteric fractures is extremely challenging due to the difficulty of obtaining and maintaining anatomic reduction and effective fixation. The purpose of this study was to describe a surgical technique for minimally invasive clamp-assisted reduction and long InterTAN nail fixation to manage Seinsheimer type V subtrochanteric fractures and report the clinical and radiological results.
methodsA retrospective study was conducted on patients with Seinsheimer type V subtrochanteric fractures between March 2015 and June 2021. A total of 30 patients treated via minimally invasive clamp-assisted reduction, long InterTAN nail fixation and selective augmentation with a cerclage cable were included. The following data were collected and evaluated: patient demographics, operative time, blood loss, reduction quality, tip apex distance (TAD), time to bone union, Harris hip score (HHS), visual analog score (VAS), and complications.
resultsThe mean age of the 30 patients was 64.8 years (range: 36-90 years). The mean operative time was 102.2 min (range: 70-150 min). The mean loss of blood was 318.3 ml (range: 150-600 ml). The reduction quality involved 27 cases of anatomic reduction and 3 cases of satisfactory reduction. The mean TAD was 16.3 mm (range: 8-24 mm). The mean follow-up time was 18.9 months (range: 12-48 months). The mean fracture healing time was 4.5 months (range: 3-8 months). The mean Harris score was 88.2 (range: 71-100), and the VAS score was 0.7 (range: 0-3). Delayed union of the subtrochanteric fracture site occurred in two patients. The limb length discrepancy, which was determined in 3 patients, was < 10 mm. There were no significant complications.
conclusionOur results indicate that minimally invasive clamp-assisted reduction with long InterTAN nail fixation is encouraging for Seinsheimer Type V subtrochanteric fractures, resulting in excellent reduction and fixation. Additionally, this reduction technique is simple, reliable, and effective in reducing and maintaining subtrochanteric fractures, particularly when intertrochanteric fractures are irreducible.
