Increasing public interest in lumbar decompression and fusion surgery in the United States: higher search volumes in the Northeast region from 2015 to 2024.
Article in Asian spine journal, 2025. 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
STUDY
designA cross-sectional study. PURPOSE: This study aimed to investigate temporal patterns, seasonal variations, and geographic differences in the US public interest in lumbar decompression and fusion surgery. OVERVIEW OF LITERATURE: The number of lumbar decompression and fusion surgery procedures for various surgical indications has significantly increased in the United States over the past few decades. As the prevalence of these procedures increases, patients are increasingly seeking online information on these procedures.
methodsThis study analyzed US public interest in lumbar decompression and fusion surgery using Google Trends data from January 1, 2015 to December 31, 2024. The relative search volume (RSV) was used to measure public interest. Temporal trends were assessed using linear regression analysis, whereas seasonal and geographic variations were evaluated using analysis of variance and Tukey's post hoc tests. Statistical significance was set at p<0.05.
resultsPublic interest in lumbar decompression and fusion surgery showed a statistically significant upward trend from 2015 to 2024 (p<0.05), with R2 ranging from 0.0141 to 0.6748 across search terms. Monthly analysis revealed that the average search volume was highest in October (78.8%) and lowest in December (68.7%). No significant differences were observed among seasons (p=0.102). Geographically, the highest mean RSV was in the Northeast (43.3%), followed by the West (19.5%), Midwest (12.6%), South (11.1%), and Southwest (10.2%), with significant differences among these regions (p<0.001).
conclusionsPublic interest in lumbar decompression and fusion surgery has shown a consistent and statistically significant upward trend over the past decade. Although seasonal variation was not significant, notable geographic differences in search volume were observed, with the northeast showing the highest level of interest. These findings highlighted regional disparities in public engagement and may serve as a basis for future healthcare resource planning and patient education strategies.
