Main features
Type of database		Describe the type of database concerned. Administrative database: Relevant administrative healthcare database most often designed for management purposes. Register: A register is a continuous collection of individual data concerning one or more health events, aiming to comprehensively include a geographically defined population, for public health/research purposes Database after investigation: Cohort studies, case-control studies, cross-sectional studies (repeated or not repeated), longitudinal studies
Study databases (details)		Cohort: A cohort consists of a set of subjects sharing a number of common characteristics that are monitored over time at an individual level to identify the occurrence of specific health events. A cohort study is based on following a pre-established protocol that involves the collection of information, as well as follow-up procedures for subjects (active or passive), so that the occurrence of specific health events may be identified without bias. Case-control study: Observational study where the characteristics and exposure of subjects with a defined pathology (the case) are compared with subjects free from the disease (the controls). Cross-sectional study: Observational study that describes that characteristics and exposure of a set of subjects collected at the time of recruitment. Longitudinal study: Observational study that describes that characteristics and exposure of set of subjects collected during successive contact with the healthcare system.
Database recruitment is carried out by an intermediary		Origin of patient recruitment: Intermediary that recruited patients to database.
Base or register (detail)		Base or register concerned
Database recruitment is is made on the basis of:		Participant selection criteria: Identification criteria for participants in the database.
Database recruitment is carried out as part of an interventional study		Interventional research corresponds to studies within the scope of biomedical research law (Hurriez-Sérusclat Law) i.e., which involves (or involved) diagnostic or therapeutic procedures or monitoring that is an additional or unusual procedure in relation to current care.
Details		Level at which intervention takes place.
Additional information regarding sample selection.		Sample selection procedures (sampling plan, means of selection and recruitment of subjects with the required inclusion criteria), or case selection and registration procedures. Example 1: A random selection is made from the electoral roll of subjects residing in Montpellier and its suburbs. 5,000 subjects were randomly drawn and contacted to participate in the study. Example 2: Cases are registered by correlating several identification sources (regional health insurance databases, discharge summaries for hospital stays [PMSI], etc.)
Main objective		Main and/or secondary objectives linked to the database. If the database objectives are changed over time, the initial database objectives are first described, followed by future objectives.
Inclusion criteria		Condition group that must be met for database inclusion.

Pathology		Indicates pathologies according to the ICD-10.
Gender		If the relevant database population consists of subjects that are: - of male sex: Male, - of female sex: Female, - Other (transsexual, etc.): Both.
Geography area		If the place of residence (or place of business, hospitalisation or birth) for individuals whose data are included in the database are distributed: - throughout several different countries: International - throughout the national territory: National (examples: throughout France, various regions, etc.) - at regional level: Regional (examples: throughout the PACA region, in all departments in Brittany except Morbihan, etc.) - at department level: Departmental (examples: throughout Gironde, in several Morbihan municipalities, etc.) - and limited to a city, well-defined canton, etc.: Local (examples: throughout Grenoble city, etc.)

Date of last collection (YYYY or MM/YYYY)		Past or planned date for the final collection of information that is included (or eligible to be included) in the database, in YYYY or MM/YYYY format. This field should not be completed if there is no fixed final date for data collection (indefinite collection period).

See "Data collection procedures" field.

Type of data collected		Type(s) of data registered in the database, given that: - administrative data usually correspond to people's identification data (such as civil status), but may cover a broader spectrum. Data are collected indirectly through administrative data sources or directly through database subjects; - biological data for biological examinations carried out specifically for the study, or following a treatment protocol whose results are included in the database; - clinical data related to medical observation. They are resulting from the observation of a person or possible symptom during medical examination. Data can be collected directly by medical staff following an ad-hoc medical examination carried out for the database, or extracts from medical records; - declarative data are data collected from individuals based on their responses to questionnaires. Individuals can complete the same questionnaires (handwritten or online self-administered questionnaires), or they can be interviewed for this questionnaire by another person according to different procedures (face to face, by email or phone);- Paraclinical data (excluding biology) are imaging, spirometry examinations, etc. that are performed.
