The INCbase project can be used to perform substudies that are part of the overall objectives of INCbase. All participants will enroll in a core module. Substudies that require collection of data not included in the core module may additionally enroll in an extended module. Some of the substudies include objectives that are supported by one or more of our partners (link to page partners). An overview of current substudies running within INCbase can be found below.
