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

Background: The relationship between blood pressure variability and hemorrhagic transformation after recombinant tissue plasminogen activator thrombolysis in patients with acute ischemic stroke is uncertain due to inconsistent methodologies across studies. This study aimed to elucidate the association between 24-h systolic blood pressure extremes post-admission and hemorrhagic transformation while considering the possibility of hemorrhagic transformation occurring beyond the initial monitoring period. Methods: We enrolled patients admitted to The First Affiliated Hospital of Harbin Medical University for ischemic stroke who were treated with intravenous recombinant tissue plasminogen activator within 4.5 h of symptom onset between January 2020 and December 2022. We analyzed the relationships among admission blood pressure, 24-h post-admission recombinant tissue plasminogen activator (mean, maximum, minimum, extreme difference, standard deviation, and coefficient of variation), immediate and 1-h post-thrombolysis blood pressure, and hemorrhagic transformation occurrence within 36 h post-thrombolysis. The potential for delayed hemorrhagic transformation was also considered during the interpretation of the results. Results: Among the 138 patients, 39.1% experienced post-thrombolytic hemorrhagic transformation. Multivariate analysis revealed that hemorrhagic transformation was significantly associated with coronary artery disease, cerebral leukoaraiosis, large cerebral infarction, elevated random glucose levels, and 24-h systolic blood pressure extremes at admission. Specifically, 24-h systolic blood pressure extremes showed a significant positive correlation with hemorrhagic transformation (OR = 1. 042; 95% CI: 1.000-1.086, Conclusion: These findings underscore the importance of establishing robust protocols for continuous blood pressure monitoring and intervention strategies tailored to individual risk profiles. Given that hemorrhagic transformation can occur beyond the initial 36 h, clinicians should maintain vigilance for delayed hemorrhagic transformation, particularly in patients with high recombinant tissue plasminogen activator. Strict control of blood pressure, especially minimizing extremes in systolic blood pressure, is essential to ensure the safety of patients undergoing thrombolysis.
