Supplementary Material for: IMPACT OF THE COVID-19 PANDEMIC ON CERVICAL CANCER SCREENING IN SÃO PAULO STATE, BRAZIL

INTRODUCTION: The early identification of precursor lesions followed by appropriate treatment prevents development of cervical cancer and its consequences OBJECTIVE: The present study evaluated the influence of the Covid-19 pandemic on cervical cancer screening by comparing the quantity of tests to detect cervical cellular changes performed in Sao Paulo state in 2019, prior to the detection of SARS-CoV-2 in Brazil, to the first (2020) and second (2021) years following its appearance. MATERIALS AND METHODS: Data from Fundação Oncocentro de São Paulo (FOSP), the agency that analyses approximately 220,000 Pap tests annually, was reviewed. RESULTS: A median of 1835 Papanicolaou (Pap) tests were performed in 55 municipalities in 2019. This was reduced to 815 tests in 2020, a 56% decrease (p = 0.0026). In 2021, the median number was 1745, a 53% increase over 2020 levels (p = 0.0233). The 26 municipalities with >1000 tests in 2020 had a median reduction from 4433 in 2019 to 2580 in 2020 (p = 0. 0046). The 29 municipalities with
