Table 6. Contribution (%) of genetic (heritability, h²) and house (c²) effects to variability in malaria and non-malaria clinical and biological phenotypes of P. falciparum (Pf) and P. vivax (Pv).

Phenotype	Acronym	N	Genetic effect	House effect
			h2 (S.E.), p-value	c2 (S.E.), p-value
A. Clinical phenotypes
Number of visits Pf+	PFA	2018	12.4 (5.7), 0.009	4.6 (2.9), 0.05 a
Number of non-malaria fever visits	NMF	2018	NE, NS	8.7 (2.9), 7 × 10−4
Number of visits Pv+	PVA	2018	20.8 (3.6), 4.6 × 10−4	NE, NS
B. Parasite biological phenotypes
Pf max parasite density	mx-PFD	857	23.7 (7.9), 1.5 × 10−4	NE, NS
Pf parasite densities	PFD	857	20.4 (4.3)	NE, NS
Pv max parasite density	mx-PVD	470	19.1 (10.5), 0.02	NE, NS
Pv parasite densities	PVD	470	14.9 (4.6)	NE, NS

h², variance due to genetics, c², variance due to house effect, S.E. the standard error; NS, not significant (p-value>0.05); NE, not estimated.
