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

backgroundCluster headache (CH) is the most painful headache disorder. Despite a large body of evidence on obesity's negative influence on migraine, its impact on cluster headache disease activity remains unexplored. We aimed to determine whether body mass index (BMI) and obesity are associated with lifetime bout occurrence and annual bout frequency in patients with episodic cluster headache (ECH).

methodsThe Korean Cluster Headache Registry (KCHR) is a prospective, multicenter registry of consecutive patients with CH over 4 years. This cross-sectional study included 316 eligible patients with ECH, with ≥ 2 years of duration of CH disease and ≥ 2 times of lifetime bout occurrence. Obesity was determined using the Asia-Pacific classification (obese: BMI ≥ 25.0 kg/m

resultsThe mean (SD) age of the patients was 37 (9.7); 50 (15.8%) were female. The mean (SD) BMI was 23.9 (3.2) kg/m

conclusionsBMI and obesity were inversely associated with lifetime bout occurrence and annual bout frequency in ECH, suggesting that neurobiological aspects of obesity may suppress cluster bout periodicity.
