COLOR IV: a multicenter randomized clinical trial comparing intracorporeal and extracorporeal ileocolic anastomosis after laparoscopic right colectomy for colon cancer.

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
introductionRight-sided colon cancer is a prevalent malignancy. The standard surgical treatment for this condition is laparoscopic right hemicolectomy, with ileocolic anastomosis being a crucial step in the procedure. Recently, intracorporeal ileocolic anastomosis has garnered attention for its minimally invasive benefits. However, there remains a paucity of rigorously designed, large-scale, international multicenter randomized controlled trials to definitively assess the safety and efficacy of intracorporeal ileocolic anastomosis in laparoscopic right hemicolectomy for right-sided colon cancer.
methodsThis study is an international, multicenter, randomized, controlled, open-label, non-inferiority trial designed to compare the safety and efficacy of intracorporeal versus extracorporeal ileocolic anastomosis in patients with right-sided colon cancer undergoing right hemicolectomy. The primary endpoint is the anastomotic leakage rate within 30 days post-surgery. The main secondary endpoint is the 3-year disease-free survival rate post-surgery. A comprehensive quality assurance protocol will be established before the trial begins, including CT review, pathological evaluation, and the standardization and assessment of surgical techniques. DISCUSSION: This study aims to evaluate the safety and efficacy of intracorporeal ileocolic anastomosis following right hemicolectomy in patients with right-sided colon cancer. The anticipated outcome is that intracorporeal ileocolic anastomosis will show an anastomotic leakage rate and a 3-year disease-free survival rate comparable to those of extracorporeal anastomosis, while offering the added benefit of faster postoperative recovery.
