Because of the logistical constraints posed by the collection of samples during birth from multiple hospitals and at unpredictable hours, as well as subject's concerns about venipuncture, we obtained data on lead levels in cord blood and current venous blood, respectively, from 323 (70.7%) and 367 (80.3%) of children participating in this study.
As well, from [ 30] we obtained data describing for each gene whether it is transcribed from a bi-directional promoter based on the existence of a shared nucleosome depleted region (NDR).
To study the use of NSAIDs, particularly COX-2 selective inhibitors such as Celecoxib and Recoxifib, we obtained data from the Medical Expenditure Panel Survey (MEPS) (Cohen 2003).
As surrogate for infection control practices, we obtained data on the related consumables for Units A and B before and during the outbreak (April September 30, 2015).
As a measure of social status, we obtained data on marital status at the time of ICU admission from the Civil Registration System [ 28].
As noted above, we obtain data on the second generation from 1995 2011 March CPS, which began collecting information on parental birthplace in the mid-1990s.
As we obtained additional data of the studies in which high risk participants were excluded [ 27, 28], the study results might not be identical to previously published data.
The biased selectivity did not depend on which stimulation period was chosen, either, as we obtained almost identical results (data not shown) when a sliding full-cycle time window was used, which was shifted gradually within the 1.5 cycles, after hemodynamic delay was adjusted.
We hope this approach will become more powerful as we obtain more data on the depth of normal mitochondrial variation throughout the world.
