Pearson r (above diagonal) and nonparametric (below diagonal) correlations were reported.
Significance levels: ∗P < 0.05, ∗∗∗P < 0.001. Number of country range (sample size): 176–209.
Data source & definition: Climatically temperature pattern (TMP), °C, average yearly temperature for 30 years, 1988–2017, the World Bank Group CCKP; Cardiovascular disease (CVD) incidence rate (per 100,000) 2017, the Institute for Health Metrics and Evaluation; Ageing indexed with life expectancy at 65 year old in 2014, United Nations; Per capita GDP PPP, measured with the per capita purchasing power parity (PPP) value of all final goods and services produced within a territory in a given year, the World Bank 2014; Urbanization, measured with the percentage of population living in urban area, the World Bank 2014; Obesity prevalence, measured with the percentage of population aged 18+ with BMI equal to or over 30 kg/m2, the World Health Organization 2014. All data were log-transformed for correlation analysis.
