The use of higher percentiles of residue level or food consumption estimates would serve to artificially inflate exposure estimates.
As these metrics are close in value, we have used the NCRI, to compare with the mean or higher percentiles of exposure.
After, we generated the list of proposed new Wnt/β-catenin pathway target genes using the highest percentile criterion and we computed the indexes of the variables.
Therefore, we used the strategy B) above, the highest percentile of likely negative controls, in our case 3' UTRs, in accordance with other ribosomal profiling papers.
To confer protection on the majority of the population of consumers, the intake at a high percentile of the distribution across consumers should be used to calculate exposure.
Associations between PCB-153 levels and ADHD-related CRS-T indices were assessed using multivariable quantile regression at the 50th and 75th percentiles of CRS-T scores, where higher percentiles reflect more adverse behaviors.
Using the percentile scores of the normative sample of the non-referred children of the YSR, ASR and TRF on the internalizing and externalizing problems scales [ 11, 12], the patients were classified in groups below the 25th percentile (low group), between 25th and 75th percentile (medium group) and above 75th percentile (high group).
Extreme wet spells are defined using the 90th percentile of rainfall above the depth of wet day.
Furthermore, we categorised the CEC count per ml and sCD146 levels as 'low' and 'high' using the 75th percentile of the interquartile range of the median value as the cutoff, as previously described (Malka et al, 2012).
Contrary to expectations, they found that a significant number of subjects with ADHD had a BMI ≥ 90th percentile (19.6%) and 7.2% had a BMI ≥ 97th percentile using the higher International Obesity Task Force cut-offs points.
