1 · What the graph read from it

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.

2 · The registry

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

Purpose: Core clerkships are foundational learning experiences, yet variability in duration exists across medical schools. Many institutions adjust core clinical experiences as part of curricular modifications to meet evolving needs in undergraduate medical education. We investigated if shortened Internal Medicine (IM) and Surgery clerkship lengths or if clerkship sequence within the academic year would have any impact on NBME subject exam scores. Methods: We examined four cohorts of third-year medical students from academic years 2017-2018, 2018-2019, 2019-2020, and 2021-2022. Individual student NBME subject exam data were compared, controlling for MCAT score and clerkship block sequence within the academic year. Results: We found no statistically significant differences in IM or Surgery NBME subject exam scores between the traditional clerkship length (2017-2019) and shortened clerkship length (2019-2022) groups. Mixed-effect regression analyses that included MCAT and block sequence as additional covariates confirmed there were no statistically significant differences in IM or Surgery exam scores between groups. Despite no change in length, the Psychiatry ( Conclusions: Shortened clerkship length is not associated with lower performance on NBME subject exams. Clerkship sequence later in the academic year is associated with higher scores. Curricular reform resulting in reduced core clerkship duration may be undertaken without adverse impact on medical knowledge.
