Summary of the comparison between individuals not carrying any risk alleles for increased body weight and individuals carrying different combinations of risk alleles representing the two associated loci on chromosome 10 and 31.

Risk allele shown in bold. P-values represent statistical comparison between the control group not carrying any risk alleles and groups carrying different combinations of risk alleles. *Only one sample was homozygous for both risk alleles and hence this should be taken into account when interpreting the data.
