For Italy, the overall sensitivity for EVI was 0.82 and the specificity was 0.91 (0.88; 0.94). For New York, the corresponding values were 0.55 (0.47; 0.64) and 0.88 (0.84; 0.91). 
    Sensitivity analysis results for Italy, under alternative \(r\) specification (i.e., \(r=\frac{1}{1.5}\)), are in Figure 5. The overall sensitivity and specificity, for \(r=\frac{1}{1.5}\), was 0.75 (0.66; 0.85) and 0.93 (0.91; 0.96).
