  1. Cohen's kappa coefficient (κ) values, p-values and 95% confidence intervals (CIs) were calculated by Rstudio Version 1.3.1073 at https://www.rstudio.com (vcd package). The κ-value in the range of 0.41–0.6 means moderate agreement26. The italics indicate a total number of monkey cases found positive or negative. Bold is used for topics only such as Kappa value, p-value and CIs.
