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
backgroundCancers of the rectosigmoid region account for a significant portion of colorectal cancers malignancies and are associated with higher rates of emergency presentation compared to other colorectal cancers. This study aims to compare emergency and elective presentations of rectosigmoid junction cancers in terms of surgical and pathological outcomes.
methodsBetween 2021 and 2025, a total of 321 patients who underwent surgery for rectosigmoid cancer were retrospectively evaluated. Patients were categorized into two groups based on the nature of their hospital admission: emergency (n=76) and elective (n=245). Demographic characteristics (age, gender, American Society of Anesthesiologists Physical Status Classification System [ASA] score), surgical details (approach, tumor location, type of operation, operative duration), postoperative complications (Clavien-Dindo classification, length of hospital stay), and pathology results (perineural invasion, lymphovascular invasion, tumor (T) and nodal (N) stage, lymph node count) were analyzed.
resultsThe mean age in the emergency group (67.93±13.36 years) was higher than in the elective group (64.42±11.65 years) (p=0.027). The emergency group had a higher frequency of open surgical approaches (p<0.001), sigmoid tumors (p<0.001), and resection with colostomy procedures (p<0.001), while the elective group had higher rates of anastomosis (p<0.001). Postoperative complications, operation duration, and length of hospital stay were all significantly greater in the emergency group (p<0.001, p<0.001, and p=0.018, respectively). Pathologically, the emergency group showed higher rates of perineural invasion (p<0.001), lymphovascular invasion (p=0.006), advanced T and N stages (p<0.001 and p=0.006, respectively), and a higher number of positive lymph nodes (p=0.006). However, there was no difference between the groups in the total number of lymph nodes removed (p=0.323).
conclusionDespite the inherent challenges of emergency presentation, adherence to principles such as complete mesocolic excision and adequate lymphadenectomy in both groups resulted in comparable pathological outcomes, demonstrating the feasibility of maintaining oncologic standards even in emergency settings. This study shows that, despite their complexity, emergency presentations do not preclude oncologically radical resections when managed with standardized protocols.
