Relationship between asymptomatic carriage of COVID-19 in pregnant women and local peak prevalence. Data from Table 1 was used to generate Figure 3. Simple linear regression was performed to investigate the relationship between the prevalence of COVID-19 in pregnant women and peak daily community prevalence at three time points: the start of the study interval, during and end of the study interval. The scatter plots demonstrated no correlation with the maximum reported daily prevalence rates at the start (R2 = 0.04, p = 0.44), during (R2 = 0.01, p = 0.65) and end of the study intervals (R2 = 0.02, p = 0.62)
