data on vs. data from


We used to say "Extract data from..." But here, the authors say "we extracted the data on..."

Which is more appropriate in English? "Data on patients" or "data from patients"?

It seems to me that they are acting from different angles and both are acceptable. I am not sure.

Methods: We extracted the data on 1,099 patients with laboratory-confirmed 2019-nCoV ARD from 552 hospitals in 31 provinces/provincial municipalities through January 29th, 2020.

    We extracted the data on 1,009 patients ... on = about.
    We extracted the data from ... from tells us the source = 552 hospitals.
