Increased Cortical Excitability in Female Migraineurs: A Transcranial Magnetic Stimulation Study Conducted in the Preovulatory Phase.

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
background and purposeThe cerebral cortex has been the focus of investigations of the pathogenesis of migraine for a long time. Transcranial magnetic stimulation (TMS) is a safe and effective technique for evaluating cortex excitability. Previous studies of the duration of the cortical silent period (CSP)-a measure of intracortical inhibition-in migraine patients have yielded conflicting results. We aimed to characterize cortical excitability by applying TMS to female migraineurs during the preovulatory phase of the menstrual cycle, in order to eliminate the effects of variations in sex hormones.
methodsWe enrolled 70 female subjects: 20 migraine with aura (MA) patients, 20 migraine without aura (MO) patients, and 30 healthy controls. We measured the CSP, resting motor threshold (rMT), and motor evoked potential (MEP) induced by TMS to evaluate cortical excitability during the preovulatory phase of the menstrual cycle.
resultsThe CSP was shorter in MA patients (88.93±3.82 ms, mean±SEM) and MO patients (86.98±2.72 ms) than in the control group (109.06±2.85 ms) (both
conclusionsWe detected a shorter CSP in both MA and MO patients. This finding may indicate the presence of motor cortex hyperexcitability, which is probably due to reduced GABAergic neuronal inhibition in migraine.
