Changes in hamstring flexibility and muscle strength during the menstrual cycle in healthy young females.

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
[Purpose] The purpose of this study was to elucidate changes in flexibility and muscle strength during the menstrual cycle in detail and to investigate the relationship between flexibility and muscle strength. [Participants and Methods] Sixteen healthy young female and eight male participants were measured during the follicular, ovulation and luteal phases. Range of motion, passive torque at the onset of pain, passive stiffness and muscle strength were measured using an isokinetic dynamometer. Additionally, electromyography was measured during muscle strength measurement. [Results] In the female group, range of motion and passive torque at the onset of pain were significantly increased during the ovulatory and luteal phases compared with the follicular phase. Passive stiffness decreased significantly during the ovulatory phase compared with the follicular phase. Isometric muscle force and electromyographic activity were significantly increased during the luteal phase compared with the ovulation phase. There was no correlation between stiffness and muscle strength. However, there was a positive correlation between electromyographic activity and muscle strength. [Conclusion] Our findings suggest that changes in flexibility during the ovulatory and luteal phases are influenced by fluctuations in sex hormones. However, the changes in muscle strength showed little relation to flexibility, suggesting the involvement of neural mechanisms.
