Plot of average time consumption for data entry procedures. Patients and study nurses could enter data to the database in two ways; they either entered data directly through eCRF or first to a pCRF whose content was subsequently transferred from pCRF to eCRF resulting in a pCRF total time. Results show that entering data through eCRF is significantly faster than the complete pCRF procedure (‑2.25 ± .99 min, p = .047). Errors bars represent standard deviation
