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
objectiveThis study aimed to identify B-mode and color Doppler features in mastocytoma cases, and to evaluate anatomical changes after a dynamic friction maneuver.
methodsA review of the high- and ultra-high-frequency color Doppler ultrasound examinations that were performed before and after a friction maneuver in clinically confirmed mastocytomas.
resultsTwelve cases met the criteria. Clinical presentation revealed solitary red, brown, pink, or yellowish macules, papules, nodules, or plaques. B-mode ultrasound showed mild hypoechoic dermal thickening, which was more evident in the superficial dermis in 91.7% of cases and diffuse in one patient (8.3%). Color Doppler imaging showed no or mild vascularity. The lesion was rubbed with mild pressure using a tongue depressor. After the maneuver, an increase in the hypoechoic dermal thickening and the dermal vascularity was detected on color Doppler.
conclusionB-mode and Doppler ultrasound can reveal an increased hypoechoic dermal thickening and dermal hypervascularity after a friction maneuver, which can support the diagnosis of mastocytoma.
