Students entering the doctor of chiropractic program at Northwestern Health Sciences University were offered three adaptive units on chemistry concepts deemed foundational for the two-course biochemistry series offered in the first two terms of the program. The effects of this remedial intervention offered to 3 incoming cohorts were assessed in a retrospective case-control approach by comparing several outcomes with a control group of similar size who started the program before the implementation of the adaptive units. Our calculations suggest that there is a positive effect of these adaptive units, in that the odds ratio for students to end the course with a grade of D or F decreased. The biggest impact on performance among 4 summative exams in the course was observed on the final exam, with an odds ratio of 2.3 to earn an A or B on the final, indicating that students who had access to the adaptive units had a substantially higher chance to earn a good grade. The odds ratio for students to earn an F or D on the final was 0.5, indicating a 50% lower risk for a low or failing score.
