Kyphoplasty for vertebral compression fractures: the blue zone effect.

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
Background: Kyphoplasty effectively treats vertebral compression fractures (VCFs) but carries risks of perioperative complications and readmissions. Blue zones, regions characterized by longevity and reduced chronic disease, provide a unique opportunity to examine how lifestyle factors may influence surgical outcomes. This study investigated how patient demographics, health status, surgical factors, and geographic location, particularly residence in a blue zone, affected kyphoplasty outcomes. Methods: A retrospective cohort review of 372 patients undergoing kyphoplasty for VCFs from January 2009 to May 2025 was conducted at a single, tertiary care institution. Patients were divided into blue zone or non-blue zone by postal codes. 1:3 propensity score matching (PSM) was used to minimize bias and multivariable logistic regression analyzed outcomes. A 10-year Kaplan-Meier survival curve was formulated utilizing a log-rank test. Results: A total of 190 patients (175 non-blue zone and 15 blue zone patients) were available after exclusion. In the unmatched cohort, tobacco usage was associated with higher 30-day readmissions. Increased length of stay (LOS) was associated with higher American Society of Anesthesiologists (ASA) scores, older age, diabetes, mechanical expansion, and greater estimated blood loss (EBL). Thoracolumbar involvement increased neurological complications, while a bilateral approach reduced incidence. Blue zone patients had significantly lower alcohol (0% Conclusions: Our findings reinforce the significance of traditional risk factors including age, ASA score, diabetes, and tobacco use, as key indicators of kyphoplasty outcomes. Blue zone kyphoplasty patients demonstrated markedly healthier lifestyles, such as reduced alcohol and tobacco use. The present small-sized matched analyses demonstrated that while lifestyle and environmental factors may delay onset of chronic disease and VCF occurrence, no detectable association was identified between blue zone residence and kyphoplasty outcomes.
