Ligation site of the inferior mesenteric vein in laparoscopic radical resection of rectal cancer: a study protocol for a multicenter randomized-controlled trial.

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
Background: The optimal level of ligation of the inferior mesenteric vein (IMV) during rectal cancer surgery remains unclear. Lymph nodes are distributed at the root of the IMV, but whether root ligation and lymphadenectomy significantly increase the number of lymph nodes harvested or improve patient prognosis remains unclear. This multicenter randomized-controlled trial was designed to compare long-term survival and short-term outcomes (surgical complications, lymph node yield, postoperative recovery) between high and low IMV ligation during laparoscopic radical rectal cancer resection. Methods: This multicenter randomized-controlled trial will enroll 1,516 patients undergoing laparoscopic-assisted radical resection for rectal cancer. Participants will be recruited and randomized (1:1) by using a dynamic minimization algorithm to balance covariates, including age, sex, American Society of Anesthesiologists classification, tumor location, body mass index, preoperative clinical stage, and neoadjuvant therapy. Patients will be allocated to either high ligation or low ligation of the IMV. The primary endpoint is 3-year disease-free survival. Discussion: The IMV ligation level is a critical yet controversial step in radical rectal cancer resection. High-level evidence is lacking regarding whether high IMV ligation improves rectal cancer prognosis, necessitating robust evidence to determine the optimal ligation level.
