a possible trendp = 0.097so close (0.05 < p ≤ 0.1)

Although a possible trend was evident, there was no significant effect of MTM on CVD mortality when analyzed over the 15 year period (F = 2.84; df = 1, 51; p = 0.097).

marginally non-significantno p-value reported

Although the highest rates of dementia were seen in counties with the highest rates of mining (e.g., Boone, Kanawha), only marginally non-significant statistical correlations were found between the number of km 2 mined and the rates of age-adjusted dementia mortality/100,000 population (Two-tailed Pearson r correlation analysis; Figure 11 a,b; both r = 0.51; p = 0.051; 15 xy pairs).

Further analyses with satellite imaging data revealed a highly significant positive correlation between the number of distinct mining sites vs. both mean and cumulative vascular and unspecified dementia mortality over the 15 year period.
