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
introductionRobot‑assisted surgery is becoming increasingly popular and its application is expanding to various spinal surgical procedures, including endoscopic spinal surgery.
aimThe aim of this study was to describe a novel small parallel orthopedic surgical robot and evaluate its feasibility in assisting surgeons during percutaneous lumbar laminectomy on cadaveric specimens. MATERIALS AND
methodsThe authors of the study developed a new orthopedic surgical navigation system (R‑Pharos, Rossum Robot Co., Ltd, Beijing, China), consisting of a navigation cart and a hybrid serial‑parallel bedside robotic arm. The system is equipped with interactive software for selecting and planning the percutaneous lumbar laminectomy target and path. A cadaveric specimen was selected for a right‑side partial laminectomy at L4. During the procedure, the surgeon used the robotic arm to guide the saw to the target lamina and perform the percutaneous resection. Postoperative cone beam computed tomography (CBCT) and endoscopic assessments were used to confirm the resection outcome.
resultsAfter optimizing the precision of the small parallel orthopedic surgical robot to 1 mm, it was shown to meet the navigational requirements for percutaneous lumbar laminectomy. The surgeon utilized the interactive software to design the resection range and path for the right L4 lamina which was successfully resected, as confirmed by endoscopic observation. A postoperative CBCT scan revealed that the resection area precisely matched the preoperative design.
conclusionsThis study demonstrated that the small parallel orthopedic surgical robot was capable of preoperatively planning the lamina resection area and could assist the surgeon in performing percutaneous lumbar laminectomy with high navigational precision.
