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
objectiveThis study investigated the clinical efficacy of personalized 3D-printed modular navigation templates for Femoral Neck System (FNS) implantation in young and middle-aged adults with femoral neck fractures. We evaluated its impact on surgical precision, safety, and radiation exposure.
methodsWe prospectively enrolled 88 patients with femoral neck fractures, randomly assigning them to either the 3D-FNS group (n = 43), which used personalized 3D-printed navigation templates for FNS guide wire insertion, or the Conventional Freehand FNS group (n = 45). We compared baseline characteristics, operative parameters (time, fluoroscopy, blood loss, guide pin adjustments, incision length), and postoperative outcomes (fracture healing time, Harris Hip Scores (HHS) at 6 months and final follow-up, and complication rates).
resultsThe 3D-FNS group showed significantly reduced operative time, intraoperative fluoroscopy count, intraoperative blood loss, and fewer guide pin adjustments compared to the FNS group (P < 0.05). While incision length was slightly longer in the 3D-FNS group, this was not significant (P > 0.05). The 3D-FNS group also had a significantly shorter fracture healing time and higher 6-month HHS (P < 0.05). Although final follow-up HHS was higher in the 3D-FNS group, the difference was not significant (P > 0.05). Complication rates (femoral neck shortening, femoral head necrosis, nonunion, internal fixation failure) were lower in the 3D-FNS group, but without statistical significance (P > 0.05).
conclusionPersonalized 3D-printed modular navigation templates significantly improve the accuracy and safety of FNS implantation, reducing operative time, fracture healing duration, and intraoperative radiation exposure. This offers an innovative and valuable solution for minimally invasive, hip-preserving treatment of femoral neck fractures in young and middle-aged adults.
