Monthly BA incidence was calculated per 10,000 live births. COVID\u201019 policy phases were defined as No NPI (Jan 2004\u2013Dec 2019), NPI (Jan 2020\u2013Nov 2022), NPI\u2010relaxation (Dec 2022\u2013Feb 2023), and Post\u2010NPI (Mar\u2013Dec 2023). Phase\u2010specific incidence rate ratios (IRRs) were estimated using Poisson regression with live births as an offset and calendar\u2010month fixed effects. Late Kasai was defined as portoenterostomy performed at age\u2009&gt;\u200960 days; phase differences were assessed using logistic regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 586 infants with BA were identified (overall incidence 1.55\/10,000). Crude incidence was 1.52\/10,000 in No NPI (485 cases), 1.64\/10,000 in NPI (73), 0.90\/10,000 in NPI\u2010relaxation (3) and 2.18\/10,000 in Post\u2010NPI (25) Compared with No NPI, adjusted IRRs were 1.08 (95% confidence interval [CI] 0.84\u20131.38) for NPI, 0.58 (0.19\u20131.82) for NPI\u2010relaxation, and 1.46 (0.98\u20132.19) for Post\u2010NPI. The proportion of late Kasai decreased from 35.3% in No NPI to 16.0% (4\/25) in Post\u2010NPI (odds ratio 0.38, 95% CI 0.14\u20131.08).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The incidence of BA in Taiwan did not decline during the COVID\u201019 NPI period, suggesting limited impact of reduced infectious exposure on BA occurrence.
