General aim: To assess the likelihood of long-term parental project fulfilment among a population of couples beginning IVF treatment.
Secondary aim: To assess the cumulative IVF success rate, treatment discontinuation and spontaneous births after stopping IVF treatment.

The main aims of the study are to qualitatively and quantitatively describe the exacerbations in a cohort of COPD patients at different levels of severity and to confirm the existence of a sub-group of patients defined as frequent exacerbators who experience a high number of exacerbations over time.
Where applicable, to determine the threshold value (number of exacerbations) that distinguishes frequent exacerbations by assuming that 3 exacerbations per year, regardless of severity, are sufficient to class the patient as a “frequent” exacerbator.

Several secondary aims will also be pursued.
To identify factors associated with frequent exacerbators.
To identify criteria more readily associated with exacerbation severity.
To confirm the link between frequent exacerbators/accelerated decline in lung function.
A validation of the VSRQ scale will be performed with the following metrics: replication; clinical validity through comparison with the St. George questionnaire; VSRQ unidimensional structure; VSRQ internal consistency; sensitivity to change; minimal important distance.

The aim of these three groups was to assess the difference between conventional and homoeopathic treatment.

The main aim is to study patient mortality at 5 years and risk factors. Secondary aims are:
– to describe the characteristics in this patient population, their cancer and treatment methods;
– to estimate the survival rate at 1, 4 and 5 years;
– to compare data obtained with data from the KBP-2000-CPHG study (same study type, centre and patient recruitment methods, patient inclusion criteria and several common items in both questionnaires).
