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
Objective: This study aimed to investigate the horizontal positioning (HP) technique for the precise lateral insertion of the helical blade guide pin during proximal femoral nail antirotation (PFNA) procedures for elderly osteoporotic patients. Methods: This retrospective study involved elderly osteoporotic patients with femoral intertrochanteric fractures treated at Tianjin Union Medical Center from January to December 2024. Patients were categorized into the HP group and the traditional true lateral view (TLV) group. The analyzed variables included fracture classification, horizontal anteversion angle (HAA), success rate of one-time lateral pin placement (SR-OLPP), pin insertion time, frequency of intraoperative lateral fluoroscopy images (FILFI), Parker's ratio index, lag screw placement, tip-apex distance (TAD), and reduction quality. Results: A total of 86 patients participated in the study (HP group: Conclusion: HP technology may enhance surgical efficiency and reduce radiation exposure while maintaining surgical safety and the accuracy of nail placement.
