“…Considering SARS-CoV-2 infection also affects sleep, we conducted an additional analysis on sleep disturbances among older COVID-19 patients, including sleep problems ( Karaogullarindan et al, 2021 ; Sârbu et al, 2022 ; Yadav, Yadav, Kumar, & Kumar, 2021 ) and insomnia symptoms ( Aly & Saber, 2021 ; Izquierdo-Condoy et al, 2022 ; L. Li et al, 2021 ; Nejad, Allahyari, Hosseinzadeh, Heiat, & Ranjbar, 2021 ; Rego de Figueiredo et al, 2023 ) were included.
