Association between ScholarRx Qmax question bank engagement and NBME CBSE and USMLE Step 1 performance.
Article in BMC medical education, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn recent years, the pass rate of the USMLE Step 1 exam has declined. Failing or delaying Step 1 can cost students time, money, and morale. Undergraduate medical curricula are increasingly supplemented with third-party resources to support successful completion of the curriculum and board exams. Empirical research on the utility of specific third-party resources for student success is needed to inform evidence-based resources and strategies to support students' success on standardized exams. To contribute to filling this gap, the present study examined the relationship between usage of specific components of the third-party resource ScholarRx and student performance on the Comprehensive Basic Science Exam (CBSE) and passing the USMLE Step 1 exam before clerkships began.
methodsTwo cohorts of students from a public medical school in the United States were included in the study: one from a Traditional discipline-based curriculum (n = 97) and one from an Integrated Organ System-based (IOS) curriculum (n = 103). ScholarRx data including usage of bricks, practice Qmax questions, flash facts, and express videos; biomedical science course averages; CBSE scores; and Step 1 outcomes were matched, de-identified, and analyzed (Traditional curriculum n = 97; Integrated Organ System curriculum n = 103). Multiple linear regression was performed to assess associations between engagement with specific ScholarRx tools and CBSE performance. Multiple logistic regression was used to investigate statistical predictors of taking and passing Step 1 on time.
resultsMultiple linear regression revealed that student use of ScholarRx practice questions (Qmax; Unstandardized B = 0.004-0.005) and biomedical science grades (Unstandardized B = 1.414-1.610) were significantly, positively associated with CBSE scores (R
conclusionThis study found that students' voluntary use of ScholarRx practice questions was associated with higher performance on the CBSE and taking and passing the Step 1 exam on schedule in both a Traditional curriculum and an IOS curriculum.
