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
purposeThis research investigates the benefits of robot-assisted navigation systems in retrograde intramedullary nailing for distal femoral fractures and contrasts their outcomes with conventional surgical methods. This is a retrospective clinical study designed to compare the outcomes of these two approaches.
methodsThis study included 56 distal femoral fracture patients treated between February 2020 and May 2023. Among them, 28 patients underwent robot-assisted retrograde intramedullary nailing (robot group), while 28 received conventional retrograde intramedullary nailing (traditional group). Surgical duration, intraoperative fluoroscopy frequency, number of guidewire insertions into the femoral medullary cavity, and intraoperative blood loss were recorded. Healing progress and fixation stability status were observed, and postoperative articular function was assessed using Neer's scoring system at a one year follow-up.
resultsBaseline characteristics were comparable between the two groups, showing no statistically significant differences.The robot group demonstrated shorter operative time, fewer guidewire placements, reduced intraoperative hemorrhage and incision size compared to the traditional group (P < 0.05). While the Neer's score for postoperative joint function showed a higher excellent-to-good rate in the robot group, no significant difference was observed between the group (P > 0.05).
conclusionCompared with traditional surgical methods, robot-assisted retrograde intramedullary fixation for fractures of the distal femur offers advantages of being minimally invasive, more precise, requiring shorter operative times, and resulting in reduced blood loss, fluoroscopy exposure, and guidewire insertion attempts. These benefits may contribute to a reduction in postoperative complications.
