Granuloma annulare subtypes: sonographic features and clinicopathological correlation.
Observational study in Journal of ultrasound, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeDiagnosis of granuloma annulare (GA) is based on the clinical and histopathological findings. However, only sporadic case reports of subcutaneous GA sonography have been published to date. The objective of this study was to evaluate the ultrasonographic patterns of the different clinical variants of GA: localized, generalized, subcutaneous, and perforating.
methodsIn this retrospective observational study, we analyzed and correlated the clinical, histopathological, and sonographic features of 15 patients diagnosed with GA.
resultsWe included 8 women and 7 men with a mean age of 48.4 years (8-77 years). We found three different sonographic patterns depending on the clinical variant of GA: poorly defined hypoechoic band including the dermis (dermal pattern), irregularly shaped hypoechoic hypodermal lumps (hypodermal pattern), and ill-defined hypoechoic dermal and subcutaneous lesions (mixed pattern). Five cases showed increased blood flow signal on Doppler interrogation.
conclusionAlthough our findings are broadly consistent with the previous reports of subcutaneous GA, the sonographic features in localized, generalized, and perforating GA have not been previously reported.
