1 · What the graph read from it

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.

2 · The registry

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

backgroundMandibular tumors significantly impact patient health and quality of life. Surgical resection is the primary treatment, often necessitating reconstruction to restore appearance and function. Traditional surgical methods rely heavily on surgeon experience, posing risks such as excessive blood loss and facial paralysis. The advent of digital and robotic-assisted surgical technologies offers improved precision and outcomes.

methodsThe study included five pairs of models with mandibular tumors, divided into a control group (traditional surgery) and an experimental group (robot-assisted surgery). In the experimental group, procedures were performed using a robot-assisted electromagnetic surgical navigation system, following alignment with the preoperative design under robotic guidance. Conversely, the control group underwent traditional surgery, where osteotomy positions were estimated empirically based on the preoperative design. Postoperative CT scans were used to compare the actual outcomes with the preoperative plans. The osteotomy accuracy and reconstruction outcome were evaluated by measuring the positional and angular errors between the preoperatively designed and actual postoperative data.

resultsThe robot-assisted group demonstrated significantly lower osteotomy distance and angle errors compared to the control group. The reconstruction outcomes in the experimental group also showed superior alignment with preoperative plans, indicating better aesthetic and functional results.

conclusionRobotic-assisted surgery for mandibular tumor resection and reconstruction enhances surgical precision and improves reconstructive outcomes compared to traditional methods. Further research with larger sample sizes and clinical settings is necessary to confirm these findings and expand clinical applications.
