Intracorporeal versus extracorporeal anastomosis in minimally invasive right colectomy: an updated systematic review and meta-analysis.
Synthesis in Techniques in coloproctology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05039762 (Intracorporeal vs. Extracorporeal Anastomosis in Patients Undergoing Laparoscopic Right Hemicolectomy for Colonic Cancer - A Prospective Cohort Study), which is not on this map.

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.

Abstract
backgroundMinimally invasive colectomy has become the standard for treatment of colonic disease in many centers. Restoration of bowel continuity following resection can be achieved by intracorporeal (IC) or extracorporeal (EC) anastomosis. The aim of this systematic review was to assess the outcomes of IC compared to EC anastomosis in minimally invasive right colectomy.
methodsA Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-compliant systematic literature search for studies assessing the outcome of IC and EC anastomosis in laparoscopic and robot-assisted right colectomy was conducted. The primary outcome of this review was postoperative complications. Secondary outcomes included operative time, blood loss, length of stay, conversion to open surgery, and bowel recovery.
resultsTwenty-five studies including 4450 patients were evaluated. 47.7% of patients had IC anastomosis and 52.3% had EC anastomosis. The weighted mean length of extraction site incision in the IC group was shorter than the EC group. The EC group had significantly higher odds of conversion to open surgery (OR 1.87, 95% CI 1-3.45, p = 0.046), total complications (OR 1.54, 95% CI 1.05-2.11, p = 0.007), anastomotic leakage (AL) (OR 1.95, 95% CI 1.4-2.7, p = 0.003), surgical site infection (SSI) (OR 1.69, 95% CI 1.4-2.6, p = 0.002), and incisional hernia (OR 3.14, 95% CI 1.85-5.33, p < 0.001) compared to the IC group. Both groups had similar rates of ileus, small bowel obstruction, bleeding, and intra-abdominal infection.
conclusionIC anastomosis was associated with significantly shorter extraction site incisions, earlier bowel recovery, fewer complications, and lower rates of conversion, AL, SSI, and incisional hernia than has the EC anastomosis.
