Correlation between 75 MHz high-frequency ultra-sound and histopathology in psoriatic lesions.
Article in Medicine and pharmacy reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: High-frequency ultrasound (HFUS) at frequencies >20 MHz is a valuable non-invasive tool for high-resolution skin imaging, enabling quantitative assessment of epidermal and dermal morphology with an axial resolution of 21 μm. Such precision supports objective monitoring of dermatoses, including psoriasis. Objectives: To compare epidermal and dermal measurements of psoriatic lesions using 75 MHz HFUS and histopathology. Methods: Thirty psoriatic papules/plaques were imaged with 75 MHz HFUS (axial resolution: 21 μm) in patients who were referred for diagnostic biopsy, measuring epidermal thickness and subepidermal hypo-anechoic zone thickness. Lesions were marked for biopsy alignment, and histologic sections were evaluated along the same axis. Spearman's correlation analyzed agreement between methods. Results: Mean epidermal thickness was 220 ± 33 μm (HFUS) vs. 215 ± 35 μm (histopathology; R = 0.82, p < 0.01). subepidermal hypo-anechoic zone thickness was 483 ± 97 μm (HFUS) vs. 448 ± 89 μm (histopathology; R = 0.88, p < 0.01). No significant inter-method differences were observed. Conclusion: 75 MHz HFUS correlates strongly with histopathology in measuring psoriatic epidermal and dermal inflammatory changes, supporting its use as a non-invasive tool for therapeutic monitoring.
