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
Robot-assisted surgery has been increasingly used in pediatric thoracic surgery. This study aimed to assess the safety and feasibility of robot-assisted thoracoscopic surgery (RATS) when applied to mediastinal tumor resection in pediatric patients. This retrospective study included pediatric individuals who underwent robot-assisted thoracoscopic resection of mediastinal lesions at our institution between April 2020 and December 2025, and their clinical records were fully analyzed. We analyzed key indicators, including operation duration, intraoperative hemorrhage, postoperative length of stay, chest tube drainage time, surgical complications and long-term follow-up results. The study cohort comprised 168 children (88 males, 80 females) with a median age of 74 (IQR 45-114) months, a weight of 21.0 (IQR 15.0-31.8) kg, and a median tumor diameter of 4.6 (IQR 3.1-6.3) cm. The median operative time was 94.5 (IQR 73.0-124.8) minutes, with an estimated blood loss of 5.0 (IQR 2.0-8.0) mL. Two patients (1.2%) required conversion to thoracotomy because of massive bleeding and severe adhesions. Postoperatively, 16 patients (9.5%) required intensive care unit (ICU) admission, with a median postoperative hospital stay (PHS) of 6.0 (IQR 5.0-8.0) days. Overall, postoperative complications occurred in 31 patients (19.3%), predominantly Clavien‑Dindo grade II complications (n = 11). Moreover, three Clavien‑Dindo grade IIIb events (1.8%) were observed, comprising two conversions to thoracotomy and one reoperation for recurrent malignancy. On univariate analysis, tumors > 5 cm and malignant pathology were significantly associated with higher complication rates and prolonged hospital stays (all P < 0.05). Furthermore, ICU admissions were significantly higher in patients with tumors > 5 cm. RATS enables safe and minimally invasive resection of pediatric mediastinal tumors in children aged ≥ 4 months or weighing ≥ 7.5 kg, yielding favorable perioperative outcomes. Moreover, tumors > 5 cm and malignant pathology were identified as significant risk factors for adverse perioperative outcomes.
