Altered renal corticomedullary differentiation on CT, Part II: a pictorial review of malignant causes.
Review in Emergency radiology, 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
The loss of corticomedullary differentiation (CMD) on contrast-enhanced CT reflects disruption of the physiologic perfusion gradient between the renal cortex and medulla. While benign and inflammatory disorders remain the most frequent causes, malignant renal processes constitute an important subset of pathology in which recognition of altered CMD may have major diagnostic and therapeutic implications. In neoplastic presentations, diffuse or segmental alterations in CMD arise from replacement, compression, or infiltration by tumor, or from the interplay of vascular and urinary obstructive mechanisms. Characteristic enhancement kinetics across the different enhancement phases may allow differentiation among various renal masses. This pictorial review focuses on the imaging hallmarks and pathophysiologic correlates of malignant renal neoplasms with associated altered CMD, highlighting multiphasic CT patterns, representative cases, and diagnostic pitfalls.
