Optimizing Chronic Migraine Care: The Impact of Advanced Practice Nurse Involvement in OnabotulinumtoxinA Administration.

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
backgroundChronic migraine is a disabling and prevalent neurological disease that significantly impacts patients' quality of life. OnabotulinumtoxinA (OnabotA) is a safe and effective chronic migraine preventive treatment. The objective was to evaluate adherence to the recommended time interval between consecutive OnabotA injections according to the Phase III Research Evaluating Migraine Prophylaxis Therapy (PREEMPT) protocol, and to analyze changes in the interval adherence before and after the introduction of an Advanced Practice Nurse (APN) in a specialized Headache Unit of a tertiary hospital.
methodsThis was a retrospective study performed in a Spanish specialized Headache Clinic. Patients diagnosed with chronic migraine and treated with OnabotA following the PREEMPT protocol were included, before and after the introduction of APNs. Treatment was considered interval-compliant if the injection interval ranged from 75 to 105 days. The data collected included three 18-month periods. Statistical analyses examined differences across periods using R-Studio.
resultsA total of 2991 participants were included, of whom 83.8% (2507/2991) were women, with a median age [interquartile range (IQR)] of 48.0 [40.0-57.0] years old. A statistically significant association between the introduction of the APN and improved adherence to the PREEMPT protocol was observed over time (Z = -19.60,
conclusionThe involvement of advanced practice nurses in OnabotA administration decreased the time interval between infiltrations and improved adherence to the PREEMPT protocol. These findings highlight the APN's role in optimizing patient care.
