TL;DR: The Norwegian Mother and Child Cohort Study had a long planning phase involving many scientists who contributed ideas that helped to design questionnaires and to structure the biobank, which is described in detail elsewhere.

TL;DR: It is suggested that prevalence estimates of exposures and outcomes, but not estimates of exposure-outcome associations are biased due to self-selection in the Norwegian Mother and Child Cohort Study.

TL;DR: Both 10 mg and 20 mg of omeprazole gave effective relief of symptoms, although 20 mg gave superior healing in patients with oesophagitis, according to a double-blind, parallel-group, placebo-controlled comparison.

TL;DR: In addition to previously known socio-demographic predictors, medical variables were important in identifying sickness absentees with an increased risk of disability pension (DP).

TL;DR: Self-reported tobacco use is a valid marker for tobacco exposure in the MoBa cohort, suggesting that underreporting of smoking in epidemiologic studies is common and may constitute a validity problem, leading to biased association measures.
