Results of the test of synchrony for incidence time series and rainfall between 1989 and 1994.

Periodic Band	1.8–2.5 years	3–4 years	4–5 years
Incidence	Entropy = 0.7043 p-value < 0.0001	Entropy = 0.7407 p-value = 0.0004	Entropy = 0.7542 p-value = 0.0360
Rainfall	Entropy = 0.7276 p-value < 0.0001	Entropy = 0.7091 p-value = 0.0041	Entropy = 0.6327 p-value = 0.0669

The test was realized in three different periodic bands and based on normalized entropy, 0 for flat distribution and a 1 for unimodal distribution.
