Note. Estimate and SE presented for the COVID-19 pandemic (vs 1 year earlier); negative estimates indicate worse health-related quality of life in 2020 than in 2019.

GH indicates Global Health; GMH, global mental health; GPH, global physical health; IPTW, inverse probability of treatment weighting; PROMIS, Patient-Reported Outcomes Measurement Information System; PS, propensity score; SE, standard error.
