Efficiency and safety of high-dose undiluted intravenous push levetiracetam loading doses compared to intravenous infusion in seizing patients: A retrospective cohort study.

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
objectiveIntravenous (IV) push (IVP) is an alternative administration method for levetiracetam, but evidence evaluating it compared to IV piggyback (IVPB) for loading doses in acutely seizing patients is limited, particularly in patients with status epilepticus (SE). This study aimed to compare the efficiency and safety of IVP versus IVPB levetiracetam loading doses.
methodsThis was a single-center sequential retrospective study conducted in adult (≥18 years) patients who received an IV levetiracetam loading dose (>2000 mg or ≥20 mg/kg) for acute or suspected seizure. The primary outcome was time to administration, compared between doses given as IVP versus IVPB. Secondary outcomes included rates of adverse events (AEs), rescue benzodiazepine or antiseizure medication administration, intubation, and intensive care unit (ICU) admission between groups.
resultsA total of 246 patients were included; 116 received IVP and 130 received IVPB loading doses. Median age was 56 years; most patients were male (62%) and White (60%) and had witnessed seizures (67%). Doses were administered for SE in 32 (27.5%) and 46 (35.4%) patients in the IVP and IVPB arms, respectively. Median time to administration was shorter in the IVP group (12 vs. 38 min, p < .001). Bradycardia (1.7% vs. 2.3%, p = .99), hypotension (7.8% vs. 12%, p = .30), sedation (6% vs. 12.3%, p = .09), intubation (10% vs. 8%, p = .37), ICU admission (32% vs. 39%, p = .31), and rescue medication administration (8.6% vs. 14.6% p = .10) were similar between groups. In SE patients, IVP was associated with shorter time to administration (12 vs. 44 min, p = .003) and lower odds of ICU admission after adjustment for age, dose, Status Epilepticus Severity Score, and seizure history (adjusted odds ratio = .23, 95% confidence interval = .06-.81). SIGNIFICANCE: IVP reduced time to levetiracetam administration versus IVPB and was not associated with more AEs. Rescue agent use, intubation, and ICU admission were similar between arms, but IVP may reduce ICU admissions in SE patients. Prospective studies should assess the effectiveness of IVP versus IVPB.
