Insights Into Retrograde Cricopharyngeus Dysfunction (R-CPD) Through Analysis of Internet Search Pattern.
Article in Laryngoscope investigative otolaryngology, 2026. 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
Objectives: To assess public awareness and interest in retrograde cricopharyngeus dysfunction (R-CPD) in the United States by analyzing trends in internet search behavior. Methods: Using Google Trends, data from Google Search queries from the United States related to R-CPD between January 2013 to May 2024 were obtained. The means of RSV from 2013 to 2018 were compared to RSV from 2019 (when R-CPD was officially defined) to the present. Comparisons of the RSV means between these two periods were performed using paired Results: Google Trends data from January 2013 through May 2024 were analyzed for 24 R-CPD-related search terms. Mean RSV values from 2013 to 2018 were compared with those from 2019 to 2024, corresponding to the period following formal description of R-CPD. The mean RSV for "R-CPD" increased by 116% (11.5 ± 3.9 vs. 24.6 ± 15.4; Conclusion: Search interest related to R-CPD has increased significantly since its formal description, suggesting rising public awareness and information-seeking behavior. Higher search volumes in metropolitan areas may reflect increased recognition, access to specialty care, or disease awareness in urban settings.
