Evolution and Effects of Caffeine Utilization Throughout Medical and Surgical Training.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objective The objective of the study is to investigate the evolution of caffeine consumption during medical education, its variation by specialty, and any potential negative impacts on medical trainees. Methods We employed a multi-institutional, anonymous questionnaire to gather data on caffeine consumption and related effects among medical trainees. The survey quantified caffeine intake and its impact on sleep, focus, and fatigue. Comparisons were drawn between medical students and residents. Statistical analysis was conducted using chi-squared tests and T-tests. Results Totaling 315 survey respondents, 211 (67%) were medical students and 104 (33%) were residents. Among resident respondents, 44 (42.3%) were surgical residents and 60 (57.7%) were medicine residents. Residents demonstrated more caffeine consumption compared to medical students (200 mg vs 152 mg, p = 0.001); no significant difference in consumption was found between surgical and medicine residents (176 mg vs 217 mg, p = 0.112). An inverse correlation was identified between caffeine intake and self-reported daily tiredness for student/resident groups (p = 0.024 and p = 0.023, respectively). No significant associations were found between the year of medical training and tiredness (p = 0.503), focusing (p = 0.105), or sleep (p = 0.178). Conclusion We demonstrated that the year of medical training does not have an impact on caffeine usage or effects, and there is no significant difference between surgical/medical residents. There is a difference between residents and medical students with a significant impact on career-related parameters such as focus and sleep, underscoring the need to further investigate caffeine usage implications in medical trainees and its long-term effects on fatigue management.
