20-Year trend of high prevalence of zero coronary artery calcium in beach cities of Southern California: A blue zone?
Article in American journal of preventive cardiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundBlue zones are longevity hotspots around the world characterized by highest concentrations of healthy centenarians. Certified blue zone communities are designed by implementation of environmental and policy changes that promote healthy behaviors.
objectiveTo examine the trends of prevalence of zero CAC, a marker of ideal cardiovascular and overall health status and burden of cardiovascular risk factors in Beach Cities/certified blue zones of Southern California and rest of California.
methodsThis is a population-based cohort study of persons aged 50 years or older in California, who underwent CAC screening between 2000 and 2019. A total of 3864 participants from Beach Cities of Southern California were identified by Zip Codes and compared with 35,537 participants from rest of California. We compared trends of prevalence of zero CAC and cardiovascular risk factors between the two groups, in 5-year intervals.
resultsAmong 39,401 participants (mean age, 58.1 years; 36% women), 13,374 (34%) had zero CAC. The prevalence of CAC = 0 was significantly higher in Beach Cities compared to the rest of California (p < 0.001). Across the study period, the prevalence of cardiac risk factors including obesity, smoking, diabetes and hypertension remain significantly lower in Beach Cities. (p < 0.001).
conclusionsThis study, shows for the first time, that higher prevalence of zero CAC in Beach Cities of California, adds validity to excellent prognosis and longevity in these areas. The impact of policy implementation and environmental changes on lifestyle patterns, cardiovascular health and healthy ageing needs to be evaluated.
