Increasing Incidence of Facial Nerve Disorders in the United States from 2007 to 2022.

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
backgroundIncidence data on Facial Nerve Disorders (FND) and Bell's palsy are currently limited. Prior epidemiological studies have estimated the incidence rate of Bell's palsy to be between 11 and 53/100,000 individuals, although the most cited incidence data are from single regions or municipalities, many of which are outdated from several decades ago.
methodsThis was a retrospective cohort study of US adults from 2007 to 2022 using the Merative™ Marketscan® Research Databases. Trends in the incidence of FND were described overall and by specific sociodemographic groups, including age, sex, region, and insurance plan type. Chi-squared and simple logistic regression analyses were performed.
resultsFrom 2007 to 2022, the total adult incidence of all FND was 30.5/100,000, and the total incidence of Bell's palsy alone was 24.5/100,000. Over the study period, there was a significant annual increase of 2.1 cases of FND/100,000 adults (95% Confidence Interval [CI] 1.8, 2.3; p < 0.001), and a significant total increase of 1.5 cases of Bell's palsy/100,000 adults (95% CI 1.2, 1.7; p < 0.001). The total incidence of FND was higher in males (33.1/100,000) than in females (28.4/100,000, p < 0.001), and greater in older age groups (p < 0.001). Additionally, the incidence of FND varied significantly by region (p < 0.001) and insurance plan type (p < 0.001).
conclusionsThis study provides up-to-date incidence rates for Bell's palsy and facial nerve disorders, based on national administrative claims data. Incidence rates of FND and Bell's palsy alone have been increasing in the United States from 2007 to 2022. LEVEL OF EVIDENCE: 3 Laryngoscope, 135:2008-2013, 2025.
