Bridging the research gap in conflict-affected countries: A multi-institutional study on medical students' research involvement and barriers in Yemen.
Article in PloS one, 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
backgroundUndergraduate research engagement plays a pivotal role in promoting evidence-based medical practice, particularly in low-resource and conflict-affected settings such as Yemen. However, multiple structural and academic barriers often limit students' ability to actively participate in research. This study aimed to assess medical students' research knowledge, attitudes, participation, and perceived barriers in a multi-institutional setting in Yemen.
methodsA cross-sectional survey was conducted among undergraduate medical students from ten universities in Yemen using a structured online questionnaire assessing research knowledge, attitudes, participation, and perceived barriers. Data were collected between April and July 2025. Statistical analyses included descriptive statistics, independent t-tests, one-way analysis of variance, and linear regression to identify factors associated with research knowledge and attitudes.
resultsA total of 1,387 students participated in the study, with a mean age of 23 years; 70.7% were male. Although most students (79.8%) agreed that research should be an integral part of medical education, only 20.5% reported having published a research paper, and 41.5% had never attempted to write one. The mean research knowledge score was low (2.8 out of 10), with no significant difference by gender. Fifth-year students demonstrated the highest knowledge scores (mean = 3.2, SD = 2.0; p = 0.003). Academic performance was a significant predictor of both research knowledge and attitudes (p < 0.001). The most frequently reported barriers were insufficient training in research methods (81.0%), inadequate research facilities and resources (76.0%), limited research opportunities (74.2%), and insufficient faculty guidance (72.3%).
conclusionParticipating medical students demonstrated generally positive attitudes toward research; however, their research knowledge and active involvement remained limited. Persistent institutional and structural barriers, including limited research training, mentorship, and infrastructure, may hinder meaningful research engagement. Strengthening research training and institutional support within undergraduate medical education may help improve research engagement in resource-limited and conflict-affected settings.
