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

introductionFindings have indicated that increased usage of mobile phones may be concomitant with higher rate of headache attacks due to the low radiofrequency electromagnetic fields (RF-EMF). The aim of this study was to determine the effects of low RF-EMF on the treatment outcome in migraine patients.

methodsThis cohort study was performed on 114 migraine patients referred to the Neurology Clinic of Golestan Hospital in Ahvaz, Southwest Iran, from September 2014 to March 2015. Patients with migraine were interviewed using a standardized questionnaire exploring mobile phones, Wi-Fi devices and fixed-line telephone use as RF-EMF sources. After 3 months, we determined patients' response to treatment. Generalized estimating equation (GEE) tests were carried out to analyze data, using SPSS version 17.

resultsOut of 114 individuals who participated, 82 (71.9%) were female and 32 (28.1%) cases were male. The number and severity of migraine headaches were correlated significantly with an increased use of mobile phones during day and Wi-Fi per week (p<0.05). The usage of fixed-line telephones had no significant relationship with the study variables (p>0.05).

conclusionIt is recommended that the patients with migraine headache limit mobile phone use and instead, use the fixed-line telephone for their daily telecommunications.
