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

backgroundMedication-overuse headache (MOH) is the most common secondary headache disorder, resulting from or leading to the frequent use of acute headache medications. Despite the availability of various treatment strategies, the optimal approach remains uncertain.

objectiveThis network meta-analysis (NMA) aimed to evaluate the comparative efficacy of different strategies for managing MOH, focusing on reducing monthly headache days.

methodsWe systematically reviewed randomized controlled trials (RCTs) comparing withdrawal strategies, including bridging therapies, the use of concurrent migraine prevention drugs, and additional education, in adult patients diagnosed with MOH. The primary outcome was the reduction in monthly headache days. Eligible studies were analyzed using a random-effects NMA model, integrating both direct and indirect evidence. Treatments were ranked using p-scores, and risk of bias was assessed using the Cochrane risk of bias tool 2.0.

resultsSixteen RCTs involving 3,000 participants were included. Compared to control, combination therapies, such as abrupt withdrawal with oral prevention and greater occipital nerve block and restriction of overused acute medication with oral prevention and Calcitonin gene-related peptide (CGRP) therapies, demonstrated the greatest efficacy, with reductions in monthly headache days of -10.6 (95% CI: [-15.03; -6.16]) and -8.47 (95% CI: [-12.78; -4.15]), respectively. Headache prevention strategies, including oral prevention (P), anti-calcitonin gene-related peptide (receptor) (CGRP(R)) therapies (A), and botulinum toxin (B) showed significant in reduction of monthly headache days, but no single initial prevention strategy demonstrates superior efficacy over the others. In contrast, abrupt withdrawal alone (W) showed no significant efficacy, with a mean difference of -2.77 (95% CI: [-5.74; 0.20]).

conclusionCombination therapies, including anti-CGRP(R) therapies and nerve blocks, appear to be the most effective strategies for MOH management, highlighting their potential as initial treatment options. While headache prevention strategies demonstrated similar efficacy, abrupt withdrawal alone was insufficient. The observed reduction in headache frequency after treatment suggests that strategies with greater efficacy may help lower the likelihood of MOH relapse.
