Association between the frequency and duration of the ISP logins and the intervention outcomes
In the current research, the usage of the ISP was varied from every primiparous woman in the intervention group. During the 3 months period of intervention, the frequency of the ISP logins ranged from 24 to 504 times (median: 81, IQR: 50–278), and the correlation between the frequency of the ISP logins and intervention outcomes was not observed. The duration of the ISP logins ranged from 756 to 4,428 min (median: 1,907, IQR: 834–2,769), and the association between the ISP usage duration and intervention outcomes was found at T1 and T2.
