Table 2. Average forest cover, forest loss, fragmentation (CFI), and change in fragmentation in the surroundings of centers of first infection and across the region.
| Average Value (<25 km from infection center) | Regional Average | p-value | ||
|---|---|---|---|---|
| Forest Cover | 0.87 | Entire region | 0.55 | 0.0052 |
| IQR | 0.45 | 0.0001 | ||
| Forest Loss | 2.92% | Entire region | 5.48% | 0.9566 |
| IQR | 7.66% | 0.0501 | ||
| Fragmentation | 0.32 | Entire region | 0.17 | 0.0062 |
| IQR | 0.20 | 0.0318 | ||
| Change in Fragmentation | 338% | Entire region | 296% | 0.0258 |
| IQR | 145% | 0.0033 | ||
| Population density per km2 | 122 | Entire region | 42 | 0.0117 |
| IQR | 51 | 0.5766 |
Regional averages are calculated for the year 2014 in 2287 circular areas (25 km radius) randomly scattered across the entire region, and in the subset of the same 2287 areas that have population density comprised within the interquartile range (IQR) of the population in the surroundings (25 km radius) of the centers of first infection. The p-values are obtained by testing (Whitney-Mann test) that the average values in the surroundings of first infection areas are significantly different from regional averages (highlighted in bold).
