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

backgroundControversy exists whether prophylactic drugs are necessary in the treatment of medication overuse headache (MOH).

objectivesTo determine comparative benefits and safety of available drugs for the treatment of MOH including elimination of medication overuse (MO).

methodsWe systematically reviewed randomized controlled trials though an extensive literature search comparing different drug effects on MOH. A random-effect network meta-analysis was conducted to rank comparative effects of interventions. Outcome improvements from baseline include responder rate defined as ≥ 50% reduction of headache frequency, proportion of patients who revert to no acute medication overuse (nMO), and reduction in monthly headache and acute medication intake frequency. Certainty of evidence was classified using the Grading of Recommendations, Assessment, Development & Evaluation (GRADE).

resultsOf 8,248 screened publications, 28 were eligible for analysis. Topiramate was found to be beneficial based on its responder rate (odds ratios [OR] 4.93), headache frequency (weighted mean difference [WMD] -5.53) and acute medication intake frequency (WMD - 6.95), with fewer safety issues (i.e., tolerability, or more adverse events) than placebo (OR 0.20). Fremanezumab, galcanezumab and botulinum toxin type A (BTA) were beneficial for increased responder rates (OR 3.46 to 3.07, 2.95, and 2.57, respectively). For reversion to nMO, eptinezumab, fremanezumab and BTA were superior to placebo (OR 2.75 to 2.64, 1.87 to1.57, and 1.55, respectively). Eptinezumab, fremanezumab, erenumab 140 mg, and BTA were more efficacious than erenumab 70 mg (OR 3.84 to 3.70, 2.60 to 2.49, 2.44 and 2.16, respectively) without differences in safety and tolerability.

conclusionDespite lower safety and greater intolerability issues, topiramate has large beneficial effects probably on increasing responder rates, reducing headache frequency, and might reduce monthly medication intake frequency. Fremanezumab, galcanezumab, and eptinezumab are promising for increasing responder rates. For reversion to nMO, eptinezumab has large beneficial effects, fremanezumab has a smaller effect. BTA might have a moderate effect on responder rates and probably has a small effect on reversion to nMO.
