Nonspecific periaqueductal gray lesions on T2WI in episodic migraine.
Article in The journal of headache and pain, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundThe specific periaqueductal gray (PAG) lesions with migraine-like headache were easily identified on conventional MR images in clinical practice, and the aim of this study is to investigate the nonspecific periaqueductal gray (PAG) lesions in episodic migraine (EM) patients based on T2 weighted imaging (T2WI).
methodsT2WI images were obtained from 18 EM patients and 18 normal controls (NC) on 3.0 T MR system. The images were observed by two experienced radiologists, and the lesions were identified on T2WI by consensus by 2 experienced neuroradiologists blinded to the patient identity. Chi-Square test was performed for the significance test.
resultsRing-like hyperintensity lesions (HILs) around the PAG region were observed in 14 EM patients and in 5 NCs on T2WI. Four EM patients and 13 NCs were normal in PAG region. The significance was revealed by Chi-Square test (P = 0.003).
conclusionHIL of PAG may be the direct evidence of the EM genesis, and the further structural and functional study should be performed to elucidate the neuromechanism of migraine pathogenesis.
