Harmonization of psoriasis data collection is needed

[Fred]

It's a great idea and could possibly begin to happen as access to data gets easier, but I think it will be a long time before the various funders of the studies are going to pass over their data as a lot of the studies are funded by big pharmaceutical companies, who will be reluctant to share

Yes that's a good point, but if they could get them to run their studies with say similar numbers or objectives it could help with cohorts.
