Eligibility was determined by cross-matching the maternal address on the birth certificate with water distribution system data obtained from local water department records.
Eligible subjects were identified by cross-matching the maternal address from birth records with information from local water companies on the location and installation year of the pipes.
Children were identified by cross-matching the maternal address on the birth certificate with data collected from water companies on the location, installation year, and diameter of all VL/AC water pipes in the Cape Cod region.
Germination percentage of this species in autumn was higher when the offspring light environment matched the maternal environment [ 17].
In the special case of interactions among full sisters (Table 2, column 1), it is the patrigenes that actually match the maternal interests because the patrigenes are equally related to all sisters (including self), as is the mother.
To minimise potential selection bias in the randomly selected controls we weighted the selection process for "random" controls to match the maternal social class distribution of mothers with dependent children in Avon from the 1991 census.
Therefore, could the mild ER stress we observe at 3100 m be simply considered a homeostatic response, slowing cell proliferation through protein synthesis inhibition and thereby resulting in a lower birth weight that matches the maternal oxygen supply?
To avoid population stratification effects on the genetic variability, samples in the compared groups were matched for the maternal country of origin.
Eligible individuals were identified by reviewing birth certificates and cross-matching the maternal address and date of birth on the certificate with information collected from water companies on the location and installation year of VL/AC pipes.
Eligible subjects were identified by reviewing more than 13,000 birth certificates and cross-matching the maternal address on the certificate with information collected from water companies on the location, installation year, and diameter of all VL/AC pipes in the water distribution system.
Eligible mothers were identified by manually reviewing over 13,000 Massachusetts birth certificates and cross-matching the maternal address on the certificate against address and water distribution data collected from local water companies which included the location, installation year, and diameter of all VL/AC water pipes in the Cape Cod area.
