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

backgroundMonoclonal antibodies targeting the calcitonin gene-related peptide (CGRP) pathway, such as fremanezumab, are effective for migraine prevention. However, their effectiveness in treating migraine complicated by medication overuse, remains underexplored.

objectiveThis systematic review aims to evaluate the effectiveness of fremanezumab in adults with migraine complicated by medication overuse.

methodsWe systematically searched PubMed and Embase (Ovid) databases for studies on fremanezumab, selecting primary studies that included adults with migraine complicated by medication overuse and reported at least one efficacy outcome. The search was performed in January 2024 and then updated in June 2024. Risk of bias for randomized controlled trials was assessed using the Cochrane Risk of Bias 2 (RoB 2) tool, while real-world studies were evaluated using both the ROBINS-I and ROB-ME tools. Data extraction and analysis followed established guidelines.

resultsOur search identified 176 records, of which 2 clinical trials and 7 real-world studies were included. Included studies recruited a total of 1422 adults with migraine complicated by medication overuse. In post hoc analyses from clinical trials, fremanezumab significantly reduced monthly migraine days, days with acute headache medication use, and Headache Impact Test (HIT-6) scores compared to placebo during a 12-week period. The real-world studies reported a reduction in monthly headache days at 6 months, and a high reversion rate from medication overuse headache (MOH) after one year of treatment.

conclusionBoth post hoc analyses from clinical trials and real-world studies support fremanezumab benefits in reducing migraine frequency, medication use, and headache-related disability in adults with migraine complicated by medication overuse. Given the limited quality of data, further real-world research with standardized reporting criteria is needed to substantiate long-term benefits and establish optimal treatment protocols.
