Outcomes in acute pulmonary embolism and their association with adherence to international recommendations around COVID-19 pandemic-induced hospital-strain: The experience in a Mexican tertiary care center.
Article in PloS one, 2026. 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
backgroundLack of adherence to international recommendations leads to worse outcomes. During the COVID-19 pandemic, the total number and proportion of hospitalized patients increased, consequently straining hospital care and hindering adherence.
aimsTo evaluate adherence to clinical guidelines at our center, before, during, and shortly after the COVID-19 pandemic-induced hospital strain, and its association with clinical outcomes, using a random, balanced retrospective cohort.
designA balanced and randomized sample of 50 patients per year between 2019 and 2022 was drawn from electronic medical records and analyzed with multivariable and logistic regression models. The primary outcome was a composite of in-hospital death, hemodynamic decompensation within the first 7 days, and in-hospital bleeding.
resultsThe global non-adherence in our study was 45.4%. The main risk factors for non-adherence were any mortality risk classification above low-risk PE and a PESI class different from class I, with ORs of 3.47 (95% CI 2.07-5.82) and 1.57 (95% CI 1.04-2.37), respectively. In both periods (COVID-19 season and non-COVID-19 season), non-adherent management strongly correlated with the composite outcome, OR = 2.36 (95% CI, 1.23-4.54). Non-adherence was also associated with worse in-hospital outcomes, with an incidence rate of the composite outcome of 21.08 per 1000 days/person (95% CI 10.97-40.51) and 47.7 per 1000 days/person (95% CI 33.39-67.50), and an attributable risk of 1.09% (95% CI -8.47%-10.64%).
conclusionsOverall, our findings highlight the need to prioritize human and material resources to ensure adherence to the standards of care for PE patients.
