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
High-frequency ultrasound (HFUS) allows non-invasive visualization of skin microarchitecture, offering quantitative assessment of dermal composition and vascularity, but its systematic use to track temporal changes in postoperative wound healing is still limited. This study aimed to describe and validate HFUS morphologic and vascular features corresponding to the biological phases of cutaneous surgical wound healing. A total of 730 patients who underwent surgical excision of skin lesions were evaluated at different postoperative intervals using high- and ultra-high-frequency ultrasound (48-70 MHz). Dermal thickness, echogenicity and vascularity were analysed with B-mode and colour Doppler imaging through quantitative and semi-quantitative methods and reproducibility was assessed using intraclass correlation coefficients (ICC) and Cohen's κ statistics. Cross-sectional analysis demonstrated a progressive structural and vascular evolution consistent with canonical healing phases: dermal thickness decreased from 2.45 ± 0.38 mm at T0 to 1.58 ± 0.21 mm at T4, while echogenicity increased from 0.5 [0-1] to 2.5 [2, 3], reflecting collagen compaction and maturation. Vascularity peaked at T2 (2.2 ± 0.5) and declined to 0.8 ± 0.3 by T4, paralleling the regression of angiogenesis. Measurement reproducibility was excellent (ICC = 0.91; κ = 0.82). HFUS morphologic patterns closely mirrored the biological sequence from inflammatory oedema through granulation and fibroplasia to collagen remodelling, providing real-time in vivo correlates of tissue repair. These findings support HFUS as a reliable, quantitative and reproducible tool for monitoring postoperative wound healing and as a potential imaging biomarker framework for early detection of abnormal scar evolution.
