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
objectiveTo evaluate the effectiveness of the leverage reduction with proximal femoral nail antirotation (PFNA) ball head screw driver for difficult-reducing intertrochanteric fracture.
methodsThe clinical data of 8 patients with difficult-reducing intertrochanteric fractures between July 2015 and February 2018 were retrospectively analysed. There were 3 males and 5 females, aged 66-89 years, with an average age of 76.3 years. According to Evans classification, there were 3 cases of type Ⅲ and 5 cases of type Ⅳ. The time from injury to operation was 2-8 days (mean, 3.9 days). All patients were reducted with ball head screw driver leverage through PFNA proximal incision during operation. The operation time, intraoperative blood loss, reduction time, and fluoroscopy times were recorded. Harris hip function score was used to evaluate the effectiveness at last follow-up.
resultsThe operation time was 52.5-83.7 minutes (mean, 68.1 minutes), the intraoperative blood loss was 49.8-96.4 mL (mean, 73.1 mL), the reduction time was 3.7-9.1 minutes (mean, 6.4 minutes), and the fluoroscopy times were 18.4-27.4 times (mean, 22.9 times). Patients were followed up 6-18 months (mean, 9.6 months). Postoperative X-ray films showed that the fracture obtained good reduction. No fracture displacement, fixation failure, and coxa vara occurred after operation. Fracture healing time was 3-6 months (mean, 4.6 months). At last follow-up, the Harris hip function score was 85-96 (mean, 91.6), with a result of excellent in 6 cases and good in 2 cases.
conclusionThe reduction of difficult-reducing intertrochanteric fracture by using ball head screw driver can obtain good reduction and reliable fixation. The method has such advantages as no more incision, and less blood loss and soft tissue injury.
