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
backgroundPauwels type Ⅲ femoral neck fractures are characterized by poor stability and high postoperative complication rates, and the optimal internal fixation regimen remains to be verified. The aim of this study was to compare the effectiveness between simple cannulated screws internal fixation and cannulated screws combined with lateral femoral neck support plate internal fixation in the treatment of Pauwels type Ⅲ femoral neck fractures.
methodsA retrospective analysis was performed on 68 patients with Pauwels type Ⅲ femoral neck fractures. Control group was treated with 3 cannulated screws internal fixation, and observation group was treated with lateral femoral neck support plate on the basis of control group. The operation time, intraoperative blood loss, hospitalization time, visual analogue scale (VAS) score, Harris Hip score (HHS) and postoperative complications were compared between two groups.
resultsThe central finding of this study is that the observation group provided significantly superior patient-reported and functional outcomes. Regarding postoperative complications, including fracture nonunion, avascular necrosis of the femoral head, and wound infection, the incidence was lower in the observation group compared with the control group. Specifically, the observation group demonstrated markedly better hip function, with HHS significantly higher than the control group at both 3-month (68.35 ± 2.37 vs. 59.41 ± 2.55, P < 0.001) and 6-month (92.06 ± 2.46 vs. 80.03 ± 5.23, P < 0.001) follow-ups. Moreover, patients in the observation group experienced substantially less pain, as reflected by a significantly lower VAS score at the critical 6-month time point (0.47 ± 0.56 vs. 1.09 ± 0.67, P < 0.001).
conclusionCompared with simple cannulated screws fixation, the combination of cannulated screws and a lateral femoral neck support plate provides more stable fixation, reduces postoperative pain, and facilitates faster recovery of hip joint function, without increasing the risk of complications. This approach allows for satisfactory fracture reduction and favorable functional outcomes, making it a reliable surgical strategy for the treatment of Pauwels type III femoral neck fractures.
