1 · What the graph read from it

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.

2 · The registry

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

Objective: To assess the cerebral blood flow regulation function in migraine patients using transcranial Doppler (TCD), and to explore the potential mechanism behind the increased risk of cerebral infarction in migraine patients. Methods: Compare cerebral blood flow regulation function between migraine patients and healthy volunteers. Compare cerebral blood flow regulation function among migraine patient groups with different grades of right-left shunt (RLS). Screen the influencing factors of cerebral blood flow regulation function in migraine patients. Results: Migraine patients exhibited decreased phase difference and breath-holding index (BHI), and increased gain (all Conclusion: The cerebral blood flow regulation function is impaired in migraine patients. Migraine patients with large amount of RLS exhibit more severe impairment of cerebral blood flow regulation compared to those without RLS. Younger age at onset and a higher RLS flow rate may be risk factors for impaired cerebral blood flow regulation in migraine patients. Impaired cerebral blood flow regulation function may be a potential mechanism underlying the increased risk of cerebral infarction in migraine patients.
