Total deliveries and total maternal syphilis prevalence per year from 2017–2022. The bar height in green represents the total number of births per year in the left panel. The bar height in the right panel represents the total maternal syphilis prevalence for that year with 95% confidence intervals. The blue section of the bar represents the percentage of patients diagnosed with syphilis during prenatal care. The yellow section of the bar represents the percentage of patients diagnosed with syphilis at delivery. *Indicates statistically significant differences (Wilson/Brown p ≤ 0.05) between total maternal syphilis prevalence proportions between years
