Figure 3. Modified Rankin Scale Score Distribution at 3 Months, Unadjusted Only for Patients With Respective Follow-up.

The modified Rankin Scale (mRS) score is a measure of disability ranging from 0, no neurological deficits, to 6, death.

^aThree-tier disability scale (none to moderate disability; severe disability; dead) with tier assignment were based on mRS scores if available and place of residence if the mRS scores were not available. None to moderate disability was considered present if the mRS score was 0 to 3 or when mRS score were not available, if the patient was residing at home. Severe disability was considered present if the mRS score was 4 to 5 or, when mRS score was not available, if the patient was residing in a nursing care facility.
