The VIP1 and VIP2 studes were international, multicenter studies of the old intensive care unit population.
The VIP2 study built on the successful VIP1 study which was published in 2017.
The data from VIP2 is currently being analyzed and published.
The first VIP2 publication has been published in Intensive Care Medicine (freely available):
