| Caffeine Mental Performance Meta-Analysis | Introduction Female athletes remain underrepresented in caffeine-based performance research, and inconsistent menstrual cycle classification further limits generalization of the current evidence. | 1 | Tan ZS (2026) | Caffeine and physical performance in female intermittent sport athletes: a systematic review and meta-analysis considering menstrual cycle phase. |
| Caffeine Mental Performance Meta-Analysis | Study quality was assessed using the Physiotherapy Evidence Database scale and Risk-of-Bias tool. | 1 | Tan ZS (2026) | Caffeine and physical performance in female intermittent sport athletes: a systematic review and meta-analysis considering menstrual cycle phase. |
| Caffeine Mental Performance Meta-Analysis | Caffeine was associated with improvements in agility (SMD = -0.62, 95% CI [-0.98 to -0.26], I 2 = 0%) and vertical jump (SMD = 0.37, 95% CI [0.05 to 0.69], I 2 = 0%) but not sprint performance (SMD = 0.03, 95% CI [-0.36 to 0.41], I 2 = 15.2%) with low heterogeneity across outcomes. | 1 | Tan ZS (2026) | Caffeine and physical performance in female intermittent sport athletes: a systematic review and meta-analysis considering menstrual cycle phase. |
| Caffeine Mental Performance Meta-Analysis | This systematic review and meta-analysis examined the effects of caffeine on physical performance in female athletes participating in intermittent sports and explored whether these effects differ between the menstrual cycle phases, within the constraints of the available literature. | 1 | Tan ZS (2026) | Caffeine and physical performance in female intermittent sport athletes: a systematic review and meta-analysis considering menstrual cycle phase. |
| Caffeine Mental Performance Meta-Analysis | This narrative review synthesizes current evidence regarding the prevalence of sleep disorders among medical students, the key risk factors contributing to impaired sleep quality, and the resulting impact on multiple domains of quality of life, including physical health, mental well-being, cognitive function, academic performance, and social functioning. | 4 | Nagabhushan S (2026) | Impact of Sleep Quality, Sleep Disturbances on Quality of Life Among Medical Students Worldwide: A Narrative Review. |
| Caffeine Mental Performance Meta-Analysis | The available literature consistently demonstrates a high prevalence of poor sleep quality among medical students, frequently exceeding 60%, with strong associations with anxiety, depression, burnout, reduced academic performance, and diminished overall quality of life. | 4 | Nagabhushan S (2026) | Impact of Sleep Quality, Sleep Disturbances on Quality of Life Among Medical Students Worldwide: A Narrative Review. |
| Caffeine Mental Performance Meta-Analysis | Sleep is a fundamental biological process essential for physical health, cognitive performance, and psychological well-being. | 4 | Nagabhushan S (2026) | Impact of Sleep Quality, Sleep Disturbances on Quality of Life Among Medical Students Worldwide: A Narrative Review. |
| Caffeine Mental Performance Meta-Analysis | Medical students represent a particularly vulnerable population for sleep disturbances due to demanding academic workloads, irregular schedules, psychological stress, and lifestyle-related factors. | 4 | Nagabhushan S (2026) | Impact of Sleep Quality, Sleep Disturbances on Quality of Life Among Medical Students Worldwide: A Narrative Review. |
