Comparative effectiveness of open versus laparoscopic resection in patients with locally advanced colon cancer: Inverse probability of treatment weighting approach.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIn Saudi Arabia, colorectal cancer is one of the most common cancers. Most of colorectal cancer cases were diagnosed at an advanced stage, making the treatment process more challenging. In this paper, we aim to investigate the differences between open and laparoscopic colectomies and factors influencing the use of these approaches in locally advanced colon cancer patients.
methodsThe study population included patients with locally advanced colon cancer at the National Guard-Health Affairs, Saudi Arabia. Descriptive and clinical data were collected for the patients diagnosed with locally advanced colon cancer from 2016 to 2021. The variables related to the locally advanced colon cancer patients' characteristics were compared with a chi-square test, Fisher's exact tests, student's t-tests, or Wilcoxon tests when appropriate. The overall survival and recurrence-free survival were computed using the Cox regression model.
resultsOf the 222 patients who underwent tumor resection, 75 (33.8%) underwent a laparoscopic colectomy. Unlike open colectomy patients, the group with laparoscopic colectomy were younger, had a higher body mass index, and had tumors in the left colon, with ≥12 harvested lymph nodes. The weighted data indicated no difference in the 5-year overall-survival, and the recurrence-free survival between the approaches [5-year overall survival, hazard ratio: 0.42, 95%CI (0.16, 1.12); recurrence-free survival, hazard ratio: 0.74, 95%CI (0.31, 1.78)].
conclusionsNo significant differences were observed between laparoscopic and open surgical approach for patients with locally advanced colon cancer.
