Table 3 Annual percent change (APC) for complicated malaria, stratified by gender

From: Clinical and epidemiological aspects of complicated malaria in Colombia, 2007–2013

Complicated cases Male Female Comparison between genders
2007 2013 APC % Trend 2007 2013 APC % Trend Test for parallelisma Test for coincidenceb
All parasite species 0.57 1.09 10.5 No change 0.25 0.80 19.9c Rising <0.001 0.006
P. vivax 0.27 0.51 10.4 No change 0.07 0.29 21.9 No change <0.001 <0.001
P. falciparum 0.26 0.53 11.0 No change 0.14 0.44 20.5c Rising 0.113 <0.001
  1. Significant data are highlighted in italics
  2. aA p value <0.05 is interpreted as the trends (slopes) between male and female are significantly different
  3. bA p value <0.05 is interpreted as the rate differences (coincidence of intercepts) between male and female are significantly different
  4. cThe 95 % CI of annual percent change (APC) is significantly different of 0 (p < 0.05)
