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
Objective: To present a detailed surgical video demonstrating the single-port (SP) robot-assisted repair of a cesarean scar defect (CSD) using the da Vinci SP system (Intuitive Surgical, Sunnyvale, CA, USA), with particular emphasis on hysteroscopic and near-infrared imaging guidance for accurate localization and excision of the defect. Methods: This case report describes a patient with symptomatic CSD who underwent SP robot-assisted repair using the da Vinci SP system (Intuitive Surgical). Concurrent hysteroscopy was performed to delineate the isthmocele from the uterine cavity and to support intraoperative orientation. Near-infrared imaging was performed to visualize the defect on the abdominal side. Because near-infrared imaging alone may not sufficiently define the true excision margin, a simultaneous multi-image display was used to enable real-time correlation between the hysteroscopic and intra-abdominal views. The excision line was carefully determined on the basis of this combined visualization, followed by controlled resection of the fibrotic tissue and multilayer uterine reconstruction. Results: The video illustrates each procedural step, including SP access, bladder dissection, hysteroscopy-assisted identification of the defect, near-infrared-guided marking of the resection margin, precise excision, and secure multilayer uterine closure. The combined visualization approach facilitated clear intraoperative orientation and identification of the defect margin, allowing precise excision and repair of the CSD while maintaining cosmetic integrity. Conclusion: This video provides an educational demonstration of a feasible SP robot-assisted technique for CSD repair. The integration of hysteroscopy and near-infrared imaging with a simultaneous multi-image display may assist in intraoperative decision-making and support precise excision and reconstruction in minimally invasive CSD surgery.
