Proportion of Japanese Patients with Multiple Basal Cell Carcinomas: The Effectiveness of Screening.
Article in Journal of plastic and reconstructive surgery, 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
Basal cell carcinoma (BCC) usually occurs as a solitary lesion but occasionally presents as multiple lesions. The proportion of multiple BCCs is 5.9%-7.1% in Asian patients. We conducted BCC screening in April 2021, focusing on the presence or absence of multiple lesions. Patients examined between April 2021 and March 2022 (161 lesions in 136 patients) were classified as the screening group (SG) and those examined between April 2020 and March 2021 (111 lesions in 103 patients) were classified as the non-screening group (NSG). The proportion of patients with multiple BCCs was significantly higher in the SG than in the NSG (15.4% and 6.8%, p = 0.04). We provisionally classified the head and neck gaze region into the 'central region' and 'peripheral region' based on gaze patterns. In the SG, the proportion of lesions in the peripheral region was higher in patients with multiple BCCs (32.6%) than in patients with a solitary BCC (14.8%). We speculate that we missed recognizing tumours in different areas, especially peripheral areas of the head and neck. Our results indicate that the increase in multiple lesion cases through screening occurred owing to more conscious observation of different regions, especially head and neck regions, thereby overcoming human gaze patterns.
