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
Erythema papulatum centrifugum (EPC), also known as erythema papulosa semicircularis recidivans, is a rare dermatological condition characterized by single or multiple annular or semi-annular centrifugally growing lesions surrounded by tiny erythematous papules typically observed on the trunk. EPC is prevalent, particularly in Japan and China, although only a few cases have been reported outside Asia. Herein, we present the case of a 47-year-old female from Thailand who experienced a pruritic annular erythematous rash on her right arm for two months. The diagnosis of EPC was established based on clinical manifestations and confirmed by histopathological examination. The lesions resolved after one month of treatment with 0.1% betamethasone valerate cream and avoiding warm weather. This case report contributes to the understanding of EPC, which may be underrecognized in clinical practice due to its self-limiting nature and frequent misdiagnosis. Furthermore, this article provides a comprehensive review of 17 previously reported cases of EPC, focusing on their detailed descriptions.
