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

purposeThis study aimed to clarify the short- and long-term outcomes of robotic surgery with or without lateral lymph node dissection (LLND) for rectal cancer at Fujita Health University Hospital, Aichi, Japan, during a self-pay period.

methodsWe retrospectively evaluated 115 consecutive patients who underwent robotic surgery for rectal cancer between September 2009 and March 2018, with a median follow-up period of 48 months. Total mesorectal excision was completed by two certified surgeons using a da Vinci S, Si, or Xi Surgical System with an entirely robotic single-docking technique. The surgical and pathological outcomes, morbidity, and oncological results were examined.

resultsLateral lymph node dissection was performed in 26 patients (22.6%). Neither conversion to open surgery nor perioperative blood transfusion occurred. Ten patients (8.7%) experienced Clavien-Dindo grade III postoperative complications. Pathologically, both the distal and radial margins were negative in all cases. The 5-year relapse-free survival rates for stages I, II, III, and IV were 93.5%, 100%, 83.8%, and not reached, respectively.

conclusionsEven in the period before coverage by the health insurance system, robotic surgery for rectal cancer performed by experienced surgeons was safe and technically feasible, with favorable perioperative results and long-term oncological outcomes, including rates of the relapse-free survival.
