Exfoliated cancer cells during intersphincteric resection for very low rectal cancer.
Article in Surgery today, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeTo investigate the frequency of exfoliated cancer cells and the efficacy of rectal washout during intersphincteric resection (ISR) in patients not receiving chemoradiotherapy (CRT) for very low rectal cancer.
methodThe subjects of this prospective study were 16 consecutive patients who underwent ISR without CRT for very low rectal cancer. Brushing cytology of the posterior anorectal wall was performed twice in each step of the ISR procedure and the samples were sent for blind cytological examination to identify exfoliated cancer cells.
resultsExfoliated cancer cells were identified in 9 of 13 patients (69%) preoperatively. The number of cancer cells identified after abdominal total mesorectal dissection decreased significantly from 94% (15/16) to 25% (4/16) after transanal irrigation with 2000 mL saline (p < 0.001). No cancer cells were identified after swabbing the anal wall following transanal dissection with purse-string closure of the distal stump. No suture-line recurrence was found during a median follow-up duration of 6 years.
conclusionExfoliated cancer cells, confirmed in 94% of patients after total mesorectal excision, could be eliminated by performing rectal irrigation after clamping the rectum proximal to the tumor and swabbing the anorectal wall during ISR.
