Study start date: January 1, 1988Actual date on which the first participant was enrolled.
This is an omnibus protocol for studying patients with cystic fibrosis. The main purpose of the study is to obtain samples and data collected during standard clinical care for future research to expand knowledge of the natural history, clinical manifestations (phenotypes) and the genetic variants (genotypes) of cystic fibrosis.

Protocol
This section provides details of the study plan, including how the study is designed and what the study is measuring.Design Details
79 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Cohort
These studies follow a group of individuals with common characteristics (such as a condition or birth year) over a specific period to study health outcomes or exposures.
How participants are selected
Participants are selected without using randomization. They may be chosen based on convenience, access, or willingness to participate. This approach is common when random selection isn’t practical.
Another way to select participants is through a probability sample, where participants are chosen randomly, so everyone has an equal chance to be included.

How information is collected
Researchers start collecting data from the present day forward, following participants over time to observe outcomes. This approach helps identify how exposures or behaviors may lead to health events in the future.Other Ways to Collect Data
Retrospective: These studies use existing medical records or past data.
Cross-sectional: These studies collect data at one single point in time.
Others: Some studies use a mix of approaches or less common designs depending on the research goal.
