Negative conversion curves estimating the cumulative probability of negative conversion of nucleic acid in nonsevere COVID-19 patients infected by the SARS-CoV-2 Omicron variant after stratifying by (a) age (age ≥ 65 years versus age<65 years), (b) gender (male versus female), (c) disease severity (moderate illness versus asymptomatic or mild illness), (d) comorbidities (comorbidities versus none), (e) vaccination (vaccinated ≥1 dose versus unvaccinated), and (f) NLR (NLR > 2.22 versus NLR ≤ 2.22).
