1: comparison of PCQ scores at baseline and during follow-up by t-test
2: PCQ values greater than the 95th percentile of the PCQ score distribution in non-exposed subjects (see ref [16]
3: among the 661 subjects without an abnormal PCQ score at baseline
4: comparison of PCQ scores between variables at each time-point of the study by GLM
