To maximize efficiency, it has been recommended that performance on these indicators be assessed using pharmacy claims data that are routinely collected as part of daily provision of medications and services [ 14, 20].
Associations between school participation, socio-ecological indicators, outcome measures and demographic indices were assessed using chi-square and odds ratios from logistic regression binary models.
(2) The health complaints indicator was assessed using a scale based on the HBSC-Symptom Checklist, which is a list of eight physical and psychological symptoms (headaches, abdominal pain, backache, feeling low, irritability, nervousness, sleeping difficulties and dizziness) to estimate their frequency during the last 6 months.
Because fluency and originality reflect two different indicators that were assessed using the same six tasks, error correlations were free to vary between each pair of indicators in order to account for task-specific variance (e.g. the error term of AUf1 was allowed to correlate with the error of AUo1).
The relationships between covariates, exposure indicators, metabolism indicators, and sex of newborn were assessed using a Wilcoxon rank sum test.
Associations between socioeconomic indicators and SPBC (70) were assessed using Pearson's correlation coefficients and multiple regression models.
