Statistical analysis of the cumulative mortality in mice infected with Colombian strain and its clones by Fisher exact nonparametric test

Strain vs. clones	Mortality in mice	Percentage (%)	P value
ColP vs. Col-C1	9/9–11/11	100–100	P = 0.7
ColP vs. Col-C5	9/9–1/13	100–7.6	P = 0.01
ColP vs. Col-C8	4/10–0/10	40–0	P = 0.01
ColP vs. Col-C10	4/10–5/10	40–50	P = 0.01
ColP vs. Col-C13	4/10–11/13	40–84.6	P = 0.00005
ColP vs. Col-C14	4/10–9/14	40–64.2	P = 0.001
ColP vs. Col-C15	4/10–4/10	40–40	P = 0.2
