Table 3.

Bivariate comparison^* of medication adherence levels for adults living with SCD who experience varying adherence barriers (N = 130).

Median	Limited adherence barriers† (N = 88)	Multiple adherence barriers‡ (N = 42)	P value
Medication adherence levels	22	20.50	.085

SCD = sickle cell disease.

^*A Mann–Whitney U test was performed to determine significant associations among variables.

^†Limited adherence barriers: the patient reported having 0 or 1 adherence barrier.

^‡Multiple adherence barriers: the patient reported having 2 or more adherence barriers.
