But what about ‘accuracy’ of self-reported use….?
Slide14FinallyCultural/country differences in research
practices: exciting and challenging Three years
: primarily spent on data collection, now we have to go
picking the fruitsOver 20 publications are plannedFantastic data set collected… (…Data graveyard?)It would be useful if there would be funding to allow consortium members and external investigators to ‘exploit’ the
data
Many
relevant
questions
to be answered beyond the scope of the current projectERANID plus..?
