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
objectivesBasicervical femoral neck fractures (FNFs) are prone to internal fixation failure owing to their inherent biomechanical instability. This study compares the efficacy of femoral neck system (FNS) and proximal femoral nail anti-rotation (PFNA) in treating basicervical FNF. MATERIALS AND
methodsA retrospective analysis was conducted on 99 patients with basicervical FNF admitted to fuzhou second general hospital from January 2020 to June 2024. Patients were divided into two groups based on the internal fixation method used: the FNS group (53 cases, average age 63.83 ± 18.80 years) and the PFNA group (46 cases, average age 69.78 ± 16.65 years). Main observation indicators included reduction quality and internal fixation-related complications, while secondary indicators included tip-apex distance, surgical time, occult blood loss, wound length, postoperative hospital stay, mortality, and Harris hip score.
resultsThe average follow-up time was 24.03 ± 9.4 months. Preoperative data were comparable between groups (P > 0.05). The PFNA group had a significantly lower overall incidence of implant-related complications than the FNS group (2.17% vs. 16.98%, P = 0.035), and the distribution of implant-related complication subtypes also differed significantly between groups (P = 0.042). No significant differences were observed in fracture reduction quality, tip-apex distance, postoperative hospital stay, or mortality (P > 0.05). The FNS group had significantly shorter incision length (4.60 ± 1.01 cm vs. 7.76 ± 1.32 cm, P < 0.001), less hidden blood loss (204.91 ± 61.66 ml vs. 391.27 ± 136.71 ml, P < 0.001), and shorter surgical time (0.62 ± 0.20 h vs. 0.70 ± 0.23 h, P = 0.048). In the full-cohort analysis including all patients with available HHS data, the Harris Hip Score was significantly higher in the PFNA group than in the FNS group (92.52 ± 4.15 vs. 89.28 ± 5.78, P = 0.002). After excluding patients with internal fixation failure, the result remained consistent, with the PFNA group showing a significantly higher HHS than the FNS group (92.78 ± 3.81 vs. 90.37 ± 4.35, P = 0.005).
conclusionsFor AO/OTA 31-B3 basicervical FNF, PFNA was associated with fewer implant-related complications and higher final follow-up HHS than FNS. The HHS result remained consistent after excluding patients with internal fixation failure. Considering the retrospective design and the small number of complication events, PFNA may be considered a favorable fixation option, but these findings should be validated in larger prospective studies.
