Evaluating the Mainstream Influence of Cardiothoracic Surgical Research: An Analysis of Google Trends Data from 2004 to 2024.
Article in Brazilian journal of cardiovascular surgery, 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
introductionPublic awareness and interest significantly influence research priorities and healthcare advancements. This study investigates the relationship between public interest, represented by Google Trends Relative Search Volume (RSV), and cardiothoracic research outputs over 21 years (2004 - 2024).
methodsA total of 26 conditions/surgeries representing eight topics of general cardiothoracic interest were identified from a review of various social media pages, society webpages, and hospital information bulletins. Data on the conditions were collected from Google Trends and PubMed®. RSV values were calculated annually, and publication counts were extracted for each condition. The study used R (v4.3.3) for all statistical analyses and predictive models.
resultsTrauma-related conditions and extracorporeal membrane oxygenation (ECMO) demonstrated increasing RSV and publication trends, with strong positive correlations (e.g., ECMO: r = 0.88, P < 0.0001). Conditions such as congenital cardiac anomalies (e.g., tetralogy of Fallot: r = -0.74, P < 0.0001) showed a negative correlation, with declining RSV despite ongoing research. Multiple regression revealed a significant positive relationship between RSV and publication counts when conditions were controlled (slope = 16.68, R2 = 0.8081, P < 0.0001). Feature importance analysis showed that "Condition" had a slightly greater influence than RSV on publication trends.
conclusionThe study demonstrates variability between public interest and research output across cardiothoracic conditions. While some conditions, such as trauma-related cases and ECMO, show alignment between public awareness and publication activity, others, including congenital anomalies, exhibit divergence.
