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 investigate the clinical efficacy of femoral neck system and hollow compression screw in the treatment of femoral neck fractures in young patients. METHODS AND MATERIALS: A retrospective study was conducted on young patients with femoral neck fractures who underwent treatment with either the Femoral Neck System (FNS) or Cannulated Cancellous Screws (CCS) between June 2018 and June 2023. The primary outcome was evaluated using the Harris Hip Score (HHS) to assess hip functional outcomes. Secondary outcomes included operative time, intraoperative blood loss, satisfactory Visual Analogue Scale (VAS) scores, fluoroscopy frequency, fracture healing time, complications, and femoral neck shortening at 3 and 6 months postoperatively.
resultsA total of 70 patients were included (35 in the FNS group and 35 in the CCS group), with follow-up ranging from 24 to 120 weeks. The mean follow-up duration was 74.22 ± 33.27 weeks in the FNS group and 75.17 ± 27.52 weeks in the CCS group. No statistically significant difference was observed in Harris Hip Scores (HHS) between the two groups. However, the fracture healing time in the FNS group (14.44 ± 2.42 weeks) was significantly shorter than that in the CCS group (16.42 ± 2.84 weeks) (P < 0.05). Similarly, the time to full weight-bearing was earlier in the FNS group (11.83 ± 3.98 weeks) compared to the CCS group (19.32 ± 4.12 weeks) (P < 0.05). The FNS group also demonstrated lower fluoroscopy frequency (P < 0.05) and superior femoral neck shortening outcomes (P < 0.05) postoperatively. Regarding complications, the FNS group exhibited a lower rate of internal fixation failure. No statistically significant differences were observed between the two groups in other perioperative parameters, postoperative efficacy metrics, or additional complication rates (P > 0.05).
conclusionFor young patients with femoral neck fractures, while both FNS and CCS achieved similar final functional outcomes, the FNS system facilitates a more favorable recovery course by promoting faster fracture healing, enabling earlier weight-bearing, and most importantly, significantly reducing the risk of major postoperative complications. These advantages are attributable to its enhanced biomechanical stability.
