Risk Factors for Serious Hypotension Induced by Intravenous Acetaminophen in Patients With Hematologic Malignancy.
Article in Pharmacoepidemiology and drug safety, 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
purposeOwing to their rapid antipyretic effects and predictable pharmacokinetic properties, acetaminophen (AAP) are commonly administered intravenously to severely ill patients. However, the potential development of hypotension as a consequence of intravenous AAP administration has not been thoroughly addressed. In this study, we aimed to identify the risk factors associated with the occurrence of serious hypotension following intravenous AAP administration during fever in patients with hematologic malignancies.
methodsThis retrospective study included hospitalized patients in the hemato-oncology department. Patients were evaluated for serious adverse drug reactions (ADRs) resulting from intravenous administration of AAP between January and December 2023 at a tertiary hospital. The control group comprised patients who received intravenous AAP but did not experience hypotension. After univariable analysis, multivariable analysis was performed to identify the risk factors for serious hypotension.
resultsThe serious hypotension group included 37 patients, while the control group had 111 patients randomized in a 1:3 ratio based on age and sex. Three risk factors were identified as increasing the likelihood of serious hypotension: body temperature prior to administration, acute kidney injury, and bacteremia. The mean arterial pressure prior to administration decreased the risk of developing serious hypotension by 0.96 times with an increase of 1 mmHg. There were no significant differences in the length of hospitalization or 90-day mortality between the two groups.
conclusionsGiven that patients with hematologic malignancies and associated risk factors may develop serious hypotension that can lead to death, it is essential to closely monitor blood pressure during intravenous administration of AAP.
