[Are secondary descriptors of headache useful in neuroimaging examinations? Results of a multicenter retrospective study of 1041 brain MRI studies].
Observational study in Revista de neurologia, 2022. 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
introductionHeadache is a common health problem in the general population. In clinical practice it is common to request neuroimaging examinations to rule out secondary headache, especially brain magnetic resonance imaging (MRI). The aim of this study is to analyze the secondary descriptors of headache-associated symptoms in brain MRI studies to assess their usefulness as predictors of potential intracranial structural abnormalities. MATERIALS AND
methodsRetrospective observational study of brain MRI studies performed due to headache in 6 centers in Andalusia between January 1 and May 30, 2019. The studies were performed on MRI machines with similar technical characteristics and imaging protocols, and were subjected to double reading by two neuroradiologists. Uni- and bivariate analyses were performed on the variables of interest: age, sex, headache-associated symptoms, and imaging findings.
resultsA total of 1041 patients who underwent brain MRI were included -mean age: 38.6 years (range: 3-86); 69.9% women-. In 737 (70.80%) cases there were no headache-associated symptoms and in the remaining patients (304 cases, 29.20%) there were headache-associated symptoms, the most frequent being: visual alterations, paresthesia, and vertigo and dizziness. Bivariate analyses showed no significant differences between groups.
conclusionsThe findings of this study suggest that symptoms accompanying headache are not associated with a greater or lesser detection of intracranial structural abnormalities in MRI. Prospective studies that overcome the limitations of the present work are needed to verify this hypothesis.
