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

objectiveThis study aimed to assess the efficacy of concurrent magnesium-sodium valproate therapy and compare it with either magnesium or sodium valproate alone in migraine prophylaxis. MATERIALS AND

methodsThis randomized single-center double-blind parallel-group controlled clinical trial study was conducted on migraine patients within the age range of 18-65 years. The subjects with at least four monthly attacks were randomly assigned to group A (n = 82) sodium valproate, group B (n = 70) magnesium with sodium valproate, and group C (n = 70) magnesium. The patients passed a one-month baseline without prophylactic therapy and then received a 3-month treatment. The characteristics of migraine, including frequency, severity, duration of the attacks, and the number of painkillers taken per month, were monthly recorded in each visit. The Migraine Disability Assessment (MIDAS) and Headache Impact Test-6 (HIT-6) scores were recorded at the baseline and after 3 months of treatment in each group. Within- and between-group analyses were performed in this study.

resultsThe obtained results revealed a significant reduction in all migraine characteristics in all groups compared to those reported for the baseline (P <  0.001). Intragroup data analysis indicated that there was no statistically significant difference in headache frequency between groups A and B in the third month (P = 0.525); nevertheless, three other parameters showed a significant reduction in group B, compared to those reported for group A in the third month (P <  0.05). On the other hand, group C could not effectively reduce measured parameters in the patients, compared to groups A and B after 3 months (P <  0.001). Furthermore, the MIDAS and HIT-6 scores significantly diminished in groups A, B, and C compared to those reported at the baseline (P <  0.001), and these changes were more significant in groups A and B than in group C (P <  0.001).

conclusionThe obtained results of this study revealed that magnesium could enhance the antimigraine properties of sodium valproate in combination therapy and reduce the required valproate dose for migraine prophylaxis.
