Non-Restorative Low Anterior Resection Is Associated with Poor Intermediate-Term Oncological Outcomes in MRI-Defined Rectal Cancer.
Article in Cancers, 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
backgroundNon-restorative low anterior resection (NRLAR) may result in inferior oncological outcomes compared to restorative low anterior resection (RLAR) and abdominoperineal resection (APR). While NRLAR is often performed when poor functional or technical challenges are anticipated, comprehensive data on its oncological outcomes remain scarce. This study aimed to retrospectively evaluate the intermediate-term oncological outcomes of patients-who underwent RLAR, NRLAR, or APR for primary rectal cancer.
methodsThis analysis included all elective NRLAR, RLAR, and APR procedures for primary rectal carcinoma performed across 11 Dutch centers from 2013 to 2020. The primary outcome was 3-year disease-free survival (DFS). Secondary outcomes included 3-year overall survival (OS) and 3-year local recurrence (LR). KaplanMeier survival analysis with log-rank testing and multivariate Cox regression analysis were employed.
resultsA total of 253 (12.5%) patients underwent NRLAR, 1109 (55.0%) RLAR, and 656 (32.5%) APR. NRLAR was associated with a lower 3-year DFS (71.4%) versus RLAR (82.0%) and APR (77.4%) (
conclusionsNRLAR is associated with poorer intermediate-term oncological outcomes. When technically feasible, restorative options should be considered, and prospective studies are required to further investigate causal relationships.
