The Relationship Between the Average Infusion Rate of Propofol and the Incidence of Delirium During Invasive Mechanical Ventilation: A Retrospective Study Based on the MIMIC IV Database.

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
backgroundDelirium is a common complication observed in intensive care units (ICUs). Propofol is one of the most widely used sedatives and is believed to be closely connected with the incidence of delirium. The study was carried out to explore the relationship between delirium and the average rate of propofol infusion.
methodsPatients who underwent invasive mechanical ventilation (IMV) while receiving propofol from the Medical Information Mart for Intensive Care IV (MIMIC IV) database were included in the study. The primary outcome was to identify the potential risk factors for the incidence of delirium and investigate the relationship between the average rate of propofol infusion and the incidence of delirium. The secondary outcome was to further analyze the relationship by subgroup analysis. Propensity score matching (PSM) was employed to minimize bias.
resultsA total of 16,956 patients (delirium: 5805; control: 11,151) were ultimately included in the study after PSM. The median diagnostic time of delirium was 18 h. An average propofol infusion rate ≥ 20 μg/(kg*h) during the initial 18 h was found to be independently significant [OR = 1.84, 95% CI = (1.72, 1.98), p < 0.001], while an average propofol infusion rate ≤ 40 μg/(kg*h) in the first hour showed no statistically significant difference in the incidence of delirium [OR = 0.95, 95% CI = (0.88, 1.02), p = 0.163]. Besides, an average propofol infusion rate ≥ 20 μg/(kg*h) was also found to be statistically significant in all the subgroup analyses.
conclusionAn average propofol infusion rate ≥ 20 μg/(kg*h) during the initial 18 h was identified as an independent risk factor for delirium, suggesting that the accumulation of propofol might be associated with an increased incidence of delirium.
