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
backgroundColorectal cancer (CRC) is a malignant tumor with high morbidity and mortality rates worldwide. With the development of medical imaging technology, imaging features are playing an increasingly important role in the prognostic evaluation of CRC. Laparoscopic radical resection is a common surgical approach for treating CRC. However, research on the link between preoperative imaging and short-term prognosis in this context is limited. We hypothesized that specific preoperative imaging features can predict the short-term prognosis in patients undergoing laparoscopic CRC resection.
aimTo investigate the imaging features of CRC and analyze their correlation with the short-term prognosis of laparoscopic radical resection.
methodsThis retrospective study conducted at the Affiliated Cancer Hospital of Shandong First Medical University included 122 patients diagnosed with CRC who underwent laparoscopic radical resection between January 2021 and February 2024. All patients underwent magnetic resonance imaging (MRI) and were diagnosed with CRC through pathological examination. MRI data and prognostic indicators were collected 30 days post-surgery. Logistic regression analysis identified imaging features linked to short-term prognosis, and a receiver operating characteristic (ROC) curve was used to evaluate the predictive value.
resultsAmong 122 patients, 22 had irregular, low-intensity tumors with adjacent high signals. In 55, tumors were surrounded by alternating signals in the muscle layer. In 32, tumors extended through the muscular layer and blurred boundaries with perienteric adipose tissue. Tumor signals appeared in the adjacent tissues in 13 patients with blurred gaps. Logistic regression revealed differences in longitudinal tumor length, axial tumor length, volume transfer constant, plasma volume fraction, and apparent diffusion coefficient among patients with varying prognostic results. ROC analysis indicated that the areas under the curve for these parameters were 0.648, 0.927, 0.821, 0.809, and 0.831, respectively. Sensitivity values were 0.643, 0.893, 0.607, 0.714, and 0.714, and specificity 0.702, 0.904, 0.883, 0.968, and 0.894 (
conclusionThe imaging features of CRC correlate with the short-term prognosis following laparoscopic radical resection. These findings provide valuable insights for clinical decision-making.
