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
purposeProximal femur shaft nonunion is a challenging problem, often occurring after malreduction that results in postoperative malalignment and decreased healing potential. Correction of malalignment is critical to achieving osseous union. Here we present a novel technique for treating proximal femur nonunions with varus malalignment using an intramedullary nail inserted through a medialized trochanteric entry point.
methodsPatients who underwent a proximal femur shaft (subtrochanteric or proximal third shaft) nonunion operation at a single level 1 academic referral centre by two attending surgeons between 1/1/2014 and 1/1/2022 were identified. Radiographic imaging was reviewed to determine initial fracture classification and calculation of coronal plane alignment (CPA), which was measured on preoperative, immediate postoperative, and final follow-up radiographs. Postoperative complications, reoperations, infections, and osseous union were also collected.
resultsTwenty-one patients with a mean age of 49.9 years (66% male) were identified. Mean preoperative CPA was 125.6 degrees, immediate postoperative mean CPA was 132.6 degrees, and mean final follow-up CPA was 131.5 degrees. Mean change in CPA from immediate postoperative films to final follow-up was a decrease of 0.4 degrees. 17 patients had follow up for a minimum of 12 months or until osseous union, and all achieved union without any major complications.
conclusionExchange nailing with an antegrade trochanteric entry nail through a medialized trochanteric starting point is a safe and effective technique in the treatment of proximal femur nonunions. This technique results in improved postoperative alignment that is sustained throughout the postoperative course, and may lead to increased rates of osseous union.
