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

backgroundPre-residency research productivity is widely regarded as a critical factor for medical students aspiring to competitive residency programs. However, its specific impact on admission to top-tier programs remains uncertain.

methodsA meta-analysis was conducted to evaluate the association between pre-residency research productivity-including total publications, first-author publications, H-index, and specialty-specific output-and admission into high-reputation or high-research ranking residency programs. A comprehensive literature search of PubMed, Embase, and CENTRAL databases (up to May 2025) identified eight studies involving 3,477 U.S. medical students across seven specialties.

resultsTotal publication volume (OR = 1.82, 95% CI: 1.21-2.74, p < 0.01) and H-index (OR = 1.93, 95% CI: 1.57-2.37, p < 0.001) were significantly associated with admission into high-reputation programs. Similar trends were observed for high research ranking programs, with total publications (OR = 1.83, 95% CI: 1.42-2.36, p < 0.001) and H-index (OR = 1.92, 95% CI: 1.15-3.20, p = 0.01) showing robust correlations. In contrast, first-author publications demonstrated non-significant associations with both reputation (OR = 4.83, 95% CI: 0.37-63.26, p = 0.23) and research rankings (OR = 4.27, 95% CI: 0.74-24.51, p = 0.10).

conclusionPre-residency research productivity may confer a measurable advantage for admission into top-tier U.S. residency programs. These findings underscore the strategic value of sustained and impactful scholarly contributions, while challenging the traditional emphasis on first-author publications.
