Correlation between MRI template and tumor resection for safety margin: a retrospective study.
Article in Journal of orthopaedic surgery and research, 2026. 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
backgroundBone tumor surgery necessitates precise assessment of resection margins to optimize patient outcomes. Magnetic resonance imaging (MRI) modalities offer valuable preoperative insights, but their correlation with anatomopathological findings remains largely underexplored.
methodsA retrospective cohort study was conducted involving 47 patients with long bone sarcomas eligible for resection surgery. Preoperative MRI scans, including T1, T2, and contrast sequences, were analyzed, and corresponding histopathological evaluations were performed postoperatively. Data analysis was conducted on SAS 9.4 using summary statistics and t-tests for comparison.
resultsMean differences in tumor measurements between preoperative MRI and histopathological assessment were measured. The observed disparities were 2.04 cm for T1, 1.92 cm for T2, and 1.55 cm for contrast sequences, with no significant variations detected between MRI modalities. Similarly, when MRI modalities were compared among themselves for tumor measurements, no significant difference was found. Most of the observed differences between MRI modalities and histopathology were < = 2 cm.
conclusionThe present study highlighted the importance of optimizing MRI utilization and surgical planning protocols to enhance the accuracy of bone tumor surgery. By addressing the challenges associated with margin analysis and integrating MRI findings with histopathological evaluations, it is possible to improve patient outcomes and advance the field of orthopedic oncology.
