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.
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
backgroundThe coronavirus disease 2019 (COVID-19) pandemic has underscored the need for effective treatment for post-infectious complications, including headaches. Owing to the variable nature of post-COVID headaches, identifying effective therapies through clinical trials is challenging and the burden on patients is often severe. This study aimed to summarize the presentation of post-COVID headache in clinical practice and evaluate its response to treatment with calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs).
methodsIn this retrospective cohort study, medical records obtained between March 2022 and May 2024 from two centers were analyzed. The study included nine patients with new-onset or significantly worsening or altered patterns of previous headaches lasting more than one month after COVID-19 infection who subsequently received CGRP mAbs. Demographics, headache frequency and severity, medication use, and quality of life were assessed before and after CGRP mAb treatment.
resultsAll patients were female (median age, 48 years), and 88.9% had headaches for more than three months despite conventional preventive therapies. Headache Impact Test-6 (HIT-6) scores were greater than 60 in all patients, and the headaches were unilateral (66.7%) and pulsating (22.2%). After CGRP mAb treatment, the monthly headache days, headache severity scores, and monthly medication days decreased significantly (median with interquartile range: 25 [15-28] to 5 [4-10],
conclusionCGRP mAbs may be considered a potential treatment option for persistent headaches following COVID-19, especially the long-COVID headaches. Their use may contribute to an improved burden of headache and quality of life and may help alleviate the psychological symptoms associated with persistent headaches.
