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

Introduction: Situs inversus totalis complicates minimally invasive surgery, and simultaneous robotic surgery for tumors of different organs is particularly challenging. Case Presentation: A 72-year-old man with situs inversus totalis receiving androgen blockade for prostate cancer developed a 40-mm muscle-invasive bladder tumor undetected on magnetic resonance imaging 7 months earlier; synchronous gastric cancer was also diagnosed. After four chemotherapy cycles, robot-assisted distal gastrectomy and radical cystectomy with an ileal conduit were performed in one session, sharing four of eight ports and lasting 10 h 27 min. The bladder showed no residual carcinoma (ypT0N0) and the gastric cancer ypT2N3aM0; he died 27 months postoperatively. Conclusion: Two major robotic resections were completed in one session, to our knowledge for the first time. Port sharing avoided a second set of incisions and a second port map, although the robot was undocked and redocked. The surgery was prolonged and followed by suspected non-occlusive mesenteric ischemia.
