. % Reduction is defined as 1- (parameter value before breakpoint/parameter value after breakpoint). For P. falciparum the final model was:

y_t = μ + φ₁(y_t-1 - μ) + φ₁₂(y_t-12 - μ) + α₁T_t-3 + α₂T_t-12 + ε_t and for P.vivax:

y_t = μ + φ₁(y_t-1 - μ) + φ₁₂(y_t-12 - μ) + α₁T_t-10 + ε_t Model selection process and all parameter values can be seen in Additional file 6. Column P (<0.05) indicates the significance of any parameter B (before breakpoint)/A(after breakpoint)
