Influence of the Covid-19 pandemic on cerebrovascular diseases in the Sao Paulo region of Brazil.
Article in Communications medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 rapid spread of covid-19 overwhelmed healthcare systems. This study aimed to investigate the impact of the covid-19 pandemic on hospitalizations and hospital deaths due to cerebrovascular diseases (CVD) in São Paulo state, Brazil.
methodsThis ecologic study evaluated the CVD hospitalizations and hospital deaths (2017-2021) by demographic features and CVD type. During the pandemic (2020-2021), segmented regression models were used to detect changes in CVD trends. We also evaluated the detrended cross-correlation between CVD deaths and hospitalization with the SARS-Cov-2 infection series.
resultsDuring the pandemic, there is a 35% reduction in CVD hospitalizations, mainly in elective admissions and ischemic stroke, but a 6.5% increase in deaths, especially in Black and Brown individuals, and those aged 20-29 years. From 2020 to 2021, Black and Brown individuals experience an earlier and more prolonged increase in hospital deaths. Ischemic CVD hospitalizations decrease in the first quarter of 2020. Older people exhibit a monthly increase of 2.9% in hospitalizations and 5.3% in deaths in the 2nd and 3rd quarters of 2021. SARS-Cov-2 infections are inversely correlated to CVD hospitalizations and directly correlated to CVD hospital deaths.
conclusionsCovid-19 pandemic negatively affects CVD hospitalizations and deaths, particularly in Black and Brown individuals. The decrease in hospitalizations and increase in hospital deaths of ischemic CVD highlights vulnerability in accessing healthcare resources during the pandemic.
