Factors for Improving Diagnosis of Skin Tumors.
Article in Journal of plastic and reconstructive surgery, 2024. 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
Background: Although several studies have investigated the accuracy of clinical diagnoses of skin tumors, specific ways to improve diagnostic accuracy have not been identified. This study investigated factors that influence the accuracy of clinical skin tumor diagnostic methods and discusses strategies to improve accuracy. Methods: Study 1 retrospectively analyzed 657 skin tumors excised at our hospital between March 2001 and March 2011. Data were extracted from surgical records to establish a diagnostic template for further research. Study 2 prospectively applied this template to aid clinical diagnosis at four facilities between April 2011 and March 2013. The clinical diagnoses were compared with the histological ones and the concordance was determined. Results: A total of 448 and 209 benign and malignant tumors, respectively, were included in Study 1. The overall diagnostic accuracy was 79.0%. In Study 2, 310 patients were clinically diagnosed using a standardized template, which did not affect the diagnostic accuracy. Age, sex, duration of disease, tumor size and location, skin tone, mobility, stiffness, and years of diagnostic experience did not significantly affect diagnostic accuracy. A high proportion of pathologically malignant tumors were clinically misdiagnosed as benign (16/22; 72%). Other clinical examinations were performed in only 35 cases. Conclusions: Auxiliary diagnostic tools such as dermoscopy and biopsies should be used to accurately diagnose malignant tumors.
