Physicians’ explicit (self-reported) attitudes toward patients (preference) or stereotypes about cooperativeness by race did not influence their decision to give thrombolysis for black versus white patients. A moderated multiple linear regression analysis showed no evidence of an interaction between self-reported attitude and patient race on thrombolysis recommendation (P = .82) (results not shown). This result remained nonsignificant after controlling for physicians’ implicit bias, race, sex, socioeconomic status (SES), and belief in thrombolysis effectiveness (P = .64).
