Notes. Constraints of σ₈, Ω_m, H₀ (in units of km s⁻¹ Mpc⁻¹), S $_{8} = σ_{8} \sqrt{Ω_{m} / 0.3}$ $_{8}=\sigma_{8}\sqrt{\Omega_{\mathrm{m}}/0.3}$ , and Γ = Ω_ch for Uchuu-SDSS voids (second column) SDSS voids (third column) and Planck 2018 best-fit values (Planck Collaboration VI 2020) (fourth column), with errors calculated as the 68% uncertainties.
