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

backgroundDespite increased atrial fibrillation (AF) and oral anticoagulation (OAC) use among patients with intracerebral hemorrhage, trends in hemorrhagic stroke (HS) incidence in AF remain unclear. We examined recent epidemiological trends, considering advances in stroke prevention and an aging population. METHODS AND

resultsA Finnish nationwide study using linked administrative registries followed 168 121 patients with incident AF (2009-2017) until the first-ever intracerebral or subarachnoid hemorrhage, death, or study end (November 2018). HS incidence rates, the proportion of fatal cases (case fatality rate %), and anticoagulant purchases within 90 days before HS were analyzed. Temporal trends were assessed using logistic and Poisson regression. A total of 1890 patients with AF (53% women, median age 80.2) experienced their first-ever HS. The average annual incidence rate was 2.82/1000 PY (95% CI, 2.72-2.92), remaining stable over 10 years (range 2.62-3.22). Age-standardized incidence rates were 2.65 (2.48-2.82) for women and 2.94 (2.70-3.15) for men. The annual case fatality rate averaged 46.5% (43.9%-49.1%) without notable temporal or sex differences. Older age was associated with higher incidence rates and case fatality rate, with an increasing proportion of patients over 84. Prior OAC use increased: in 2009, 67% were not on OACs but by 2018, one third used warfarin, one third direct OACs, and only one third were without any OAC. No association was found between anticoagulation and HS case fatality.

conclusionsAmong the population with incident AF, we observed a stable first-ever HS incidence rate and short-term case fatality over the past decade despite a marked increase in prior oral anticoagulation use and aging.
