Gout flares following acute stroke: a single-center cohort and a systematic review/meta-analysis.

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
backgroundWith the global prevalence of hyperuricemia and gout rising, accumulating evidence has linked acute gout flares to a transient rise in major adverse cardiovascular events, including myocardial infarction and stroke. However, the reverse association, whether acute stroke is associated with an increased incidence of gout flares, has been inadequately investigated. The aim of this single-center cohort study, coupled with a systematic review and meta-analysis, was to evaluate the incidence and characteristics of gout flares in the early post-stroke period.
methodsA systematic review and meta-analysis of published studies was conducted, incorporating data from a cohort of acute stroke patients admitted to a tertiary care stroke center. Eligible studies reported in-hospital gout flares among patients with acute ischemic or hemorrhagic stroke. Pooled estimates were calculated using random-effects models. The systematic review was pre-registered in PROSPERO (CRD420251061747).
resultsWe identified three studies (one involving only acute ischemic stroke, two including both ischemic and hemorrhagic stroke), encompassing a total of 13,722 acute stroke patients, including our institutional cohort. The pooled incidence of in-hospital gout flares was 4% (95% CI, 2-6%; I²=88.1%). The pooled mean time to flare onset was 6.3 days post-stroke (95% CI, 4.09-8.44; I²=96.6%), and 64% of flares involved the paretic limb (95% CI, 33-90%; I²=62.1%). Among flare patients, 85% were male (95% CI, 40-100%; I²=84.5%), 97% had ischemic stroke (95% CI, 94-99%; I²=0%), and 61% were newly diagnosed with gout or hyperuricemia during hospitalization (95% CI, 48-73%; I²=0%). In our cohort, 50% and 12.5% of flare patients presented with delirium and aphasia, respectively; all patients received colchicine treatment with complete symptom resolution.
conclusionsGout flares occur in one out of every 25 acute stroke patients, particularly in men presenting with acute ischemic stroke within the first week after symptom onset, and frequently involve the paretic limb. In over half of cases, the flare uncovers previously undiagnosed gout or hyperuricemia, emphasizing the need for systematic evaluation, particularly in patients with delirium or impaired communication, where diagnosis may be delayed. Early colchicine initiation warrants consideration given its anti-inflammatory effects and potential to reduce stroke recurrence.
