Diagnostic value of dual-source CT dual-energy technology for assessing differentiation degree and serosal invasion in colorectal cancer: A retrospective study.
Article in Medicine, 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
To evaluate the diagnostic efficacy of dual-source CT (DSCT) dual-energy technology in determining the differentiation degree and presence of serosal invasion in colorectal cancer (CRC), using normalized iodine concentration (NIC), electron density, and effective atomic number (Z) as diagnostic markers. A retrospective analysis was conducted on 102 patients clinically diagnosed and pathologically confirmed with CRC. Dual-energy images from both arterial and venous phases were obtained using third-generation DSCT. NIC values were computed. The study analyzed the diagnostic value of DSCT dual-energy technology, utilizing multiple parameters, in assessing the differentiation degree of CRC and the presence of serosal invasion. For differentiating high/moderate differentiation from low differentiation, the AUCs of NIC and Z were 0.899 and 0.914 in the arterial phase and 0.865 and 0.891 in the venous phase, respectively. For detecting serosal invasion, the arterial-phase AUCs of NIC and Z were 0.963 and 0.944, respectively, and the venous-phase AUC of NIC was 0.962. ρ showed no significant diagnostic value in these comparisons. DSCT dual-energy technology, through NIC and effective atomic number, offers significant diagnostic value for evaluating both the differentiation degree and serosal invasion in CRC, providing a novel approach for preoperative assessment.
