All samples within each batch were scored in reference to the control.
Allele size was scored in reference to ABI PRISM GS (LIZ) internal size standards using the program Geneious version 6.1.6 (Biomatters Ltd., Auckland, New Zealand).
These scales were scored in reference to a normal population (the 1998 general US population, standard form) with a transformed mean of 50, and a standard deviation of 10 [ 32].
However, if only one of the repeat was represented in the RESCAN library, it would behave as single copy and be scored in the reference-independent discovery.
Errors were scored in several categories: reference memory errors, first entries on each day into a reference memory arm; errors of commission, repeat entries into arms that had been visited before on that session (i.e., working memory errors), and errors of omission, which represented failures to obtain a reward within the time limit of testing (10 min for each daily session).
The reference population was scored in relation to the splenius and hamulus muscle and coronoid processes, while these tender spots were not included in our study.
Articles were systematically scored in reference to quality, to determine level of evidence.
Importantly, only reference embryos were scored >3 in both lower and higher BNF-ANF co-exposure treatments, providing further evidence of PAH-resistance in the Elizabeth River (resistant) embryo population.
Unlike the sub-scales, the PCS and MCS are scored so that in the reference population the mean is 50, and the standard deviation is 10, meaning that 95% of the population score in the range 30 70.
Studies that did not include GP73 and AFP in the reference standard were scored "yes", and studies that included GP73 and AFP in the reference standard were scored "no".
