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

purposeUrachal cyst is a type of congenital anomaly that may undergo malignant transformation. Partial cystectomy with MATERIALS AND

methodsThe patient is a 76-year-old woman. She was referred to urology for a tumor at the dome of the bladder. Cystoscopy revealed a round submucosal mass at the dome of the bladder. The possibility of a urachal tumor could not be excluded. Since she was already diagnosed with rectal cancer and scheduled to undergo robot-assisted laparoscopic proctosigmoidectomy, we performed robot-assisted partial cystectomy during the same operative session.

resultsThe rectum was removed by a surgeon with robot-assistance. Then we detached the median umbilical ligament from just below the umbilicus toward the bladder. Both medial umbilical ligaments were dissected from abdominal wall to the dome of the bladder. A simultaneous cystoscopic light depicted the bladder boundaries of the mass with the Firefly

conclusionsRobot-assisted partial cystectomy for urachal tumors is technically feasible. NIRGS should be considered in selected cases.
