Table 2. Multivariable Random Slope Mixed-Effects Model of Changes in Desire to Avoid Pregnancy Score, March 16, 2019, to March 15, 2021.

Main model and time^a	Coefficient (95% CI)^b	Slope^c	P value
Main model and time^a	Coefficient (95% CI)^b	Slope^c	Slope differs from 0	Change in slope from prior slope
Before summer 2020 surge	−0.06 (−0.07 to −0.04)	−0.06 (−0.07 to −0.04)	<.001	Not applicable
After summer 2020 surge	0.11 (0.02 to 0.19)	0.05 (−0.03 to 0.13)	.25	<.001
After fall 2020 surge	−0.16 (−0.35 to 0.03)	−0.11 (−0.26 to 0.04)	.14	.10

^{^a}

Time is treated continuously; coefficients and slopes are reported in quarters (eg, per 3 months).

^{^b}

Model includes participant age, race and ethnicity, parity, partnership and cohabitation, food insecurity, and recruitment site. The Desire to Avoid Pregnancy score is on a range of 0 to 4 points, with 4 indicating greater desire to avoid pregnancy.

^{^c}

Slope between change points can be derived by summing coefficients.
