Fig 6. Association of mid-pandemic changes in PROMIS scores relative to pre-pandemic with changes in percentages of REM and deep sleep on free (non-work) days.

A) Increasing PROMIS scores during pandemic are associated with decreases in the amount of REM sleep received during the pandemic relative to pre-pandemic (R² = 0.269, β = -0.518, p = 0.033). B) Increasing PROMIS scores during pandemic are associated with decreases in the amount of deep sleep received during the pandemic relative to pre-pandemic (R² = 0.248, β = -0.498, p = 0.035).
