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
Objectives: This study aimed to evaluate the safety and long-term outcomes of a one-stage resection and anastomosis approach without preoperative decompression in patients with left-sided incomplete obstructive colorectal cancer. Methods: We conducted a retrospective analysis of 571 patients diagnosed with pT3-4NanyM0 left-sided colorectal cancer who underwent radical resection and primary anastomosis without preoperative decompression or a diverting stoma from April 2012 to December 2019. Of these, 97 (17%) patients presented with incomplete obstruction, while 474 (83%) had no obstruction. Incomplete obstruction was characterized by the inability of a small-caliber endoscope to pass through the tumor without necessitating emergency surgery or decompression due to bowel obstruction. We compared perioperative short-term outcomes, as well as the 5-year overall survival rate and the 5-year relapse-free survival rate between the two groups. Results: Patients in the incomplete obstruction group experienced significantly longer median intervals between admission and surgery (6 vs. 2 days, P<0.001), higher complication rates (25.8% vs. 15%, P=0.016), and longer median postoperative hospital stays (10 vs. 9 days, P=0.002). However, the rates of anastomotic leakage (2.1% vs. 2.3%, P=1), the 5-year overall survival (91.5% vs. 93.7%, P=0.436), and the 5-year relapse-free survival (80.2% vs. 85.6%, P=0.195) were comparable between the groups. Conclusions: The outcomes regarding anastomotic leakage and long-term survival for one-stage resection and anastomosis without preoperative decompression in cases of incomplete obstructive colorectal cancer are promising. This management strategy appears feasible and safe with appropriate preoperative bowel preparation.
