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

Robot-assisted partial nephrectomy (RAPN) is a common, minimally invasive procedure for localized renal tumors but carries a rare risk of life-threatening CO2 embolism. We report an 83-year-old man who developed cerebral embolism from pulmonary CO2 embolism during retroperitoneal RAPN. Intraoperative transesophageal echocardiography (TEE) revealed gas entry into the right heart, a right-to-left shunt, and subsequent gas entry into the left heart system. Postoperatively, MRI confirmed brain infarctions, but the patient was managed conservatively and showed significant recovery. This case demonstrates that maintaining the low pneumoperitoneum pressure, prompt recognition, and appropriate interventions (including TEE and supportive care) may prevent deleterious outcomes.
