Table 3.

Incidence rate ratios for the associations of recruiting and assessing infants pre-COVID-19 compared to missed due to COVID-19 between groups.

Variable	Incidence rate ratio	95% confidence interval	p-value
Recruitment in both groups	1.2	0.9–1.6	0.131
Assessment in both groups	3.3	2.4–4.5	<0.001**
Recruitment in infants with CHD	2.1	1.3–3.5	0.003**
Recruitment in HC infants	1.8	1.3–2.5	<0.001**
Assessment in CHD infants	6.6	3.7–11.5	<0.001**
Assessment in HC infants	1.9	1.3–2.9	0.001**

Note. This table indicates the likelihood of recruiting eligible infants into our study and the likelihood of currently enrolled infants having study assessments performed before March 2020 (pre-COVID) compared to between March 2020 and July 2020 (missed due to COVID-19). For instance, infants in both groups were 3.3 times more likely to be assessed pre-COVID-19 compared to missed due to COVID-19.

^a CHD = Congenital Heart Disease. ^b HC = Healthy Controls.
