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

aimsClinical trials for calcitonin gene-related peptide (CGRP) inhibitors excluded the concomitant use of onabotulinumtoxinA; thus, there is a lack of efficacy and safety data of the combined therapies. Our study aims to examine the effectiveness of CGRP inhibitors with onabotulinumtoxinA by evaluating migraine reductions in headache days and severity.

methodsSeventeen patients with chronic migraines were identified who had a partial or poor response to onabotulinumtoxinA, and were placed on dual therapy with a CGRP inhibitor. Patients' initial headache days and severity ratings were compared to final values taken 1-6 months after adding the CGRP inhibitor to their treatment regime. Comparisons between headache days and severity ratings prior to and during dual treatment were performed utilizing the Kruskal-Wallis test. The significance was set at p < 0.05.

resultsOf 17 patients (16F/1 M), n = 9 were taking fremanezumab, n = 4 were taking erenumab, and n = 4 were taking galcanezumab. Patients' average headache days per month was reduced from 27.6 ± 4.8 initially to 18.6 ± 9.4 post-treatment (p = 0.00651), and their average pain level was reduced from 8.4 ± 1.4 out of 10 to 5.4 ± 2.5 (p = 0.00074). No serious adverse side effects were reported from patients on dual therapy.

conclusionPatients with suboptimal response to onabotulinumtoxinA may benefit from CGRP inhibitors' addition to their migraine regimens. Placebo-controlled randomized studies are advised to corroborate this finding.
