Review in Dermatologie (Heidelberg, Germany), 2025. 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
backgroundKeratinocyte skin cancers (KC), including basal cell carcinoma (BCC) and the spectrum of squamous cell carcinoma (SCC), represent the most common malignancies worldwide. Accurate diagnosis and margin assessment are critical for optimal treatment but remain challenging when relying solely on clinical and dermoscopic evaluation. Reflectance confocal microscopy (RCM) offers high-resolution, noninvasive imaging of skin architecture at near-histological levels, potentially improving diagnostic precision and reducing the need for (re)biopsies.
objectiveTo evaluate the current diagnostic criteria, diagnostic utility, advantages, and limitations of confocal microscopy in the assessment of nonmelanoma skin cancer (NMSC).
methodsA narrative review of recent literature and current guidelines was conducted, focusing on RCM for the detection, characterization, and monitoring of BCC and KC. Key diagnostic criteria, imaging protocols, and clinical applications were analyzed, including preoperative mapping, differentiation from benign lesions, and follow-up after treatment.
resultsRCM provides real-time visualization of tumor architecture, cellular morphology, and vascular patterns, facilitating the identification of hallmark features such as basaloid tumor islands in BCC and keratinocyte atypia in SCC. Studies report improved diagnostic accuracy and reduced rates of unnecessary excisions. Limitations include restricted imaging depth and the requirement for operator expertise.
conclusionRCM represents a powerful adjunct to conventional diagnostic methods for NMSC. Its ability to deliver high-resolution, noninvasive imaging enhances diagnostic confidence, supports surgical planning, and aids in treatment monitoring, ultimately improving patient care. Combining multiple noninvasive techniques with proper training is key to enhancing this approach and promoting its routine clinical use.
