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
objectiveThe current analysis study aims to estimate the role of vitamin D levels and supplementation on fertility reservation expressed as ovulation rate, pregnancy rate, and anti-Müllerian hormone (AMH).
methodA systematic literature review was conducted, and 2111 females were recruited to the current study. Inclusion criteria of the current study included comparative studies evaluating the role of vitamin D status and vitamin D supplementation on fertility parameters. Included studies published till December 2023. Continuous mode with random effect, were used for the analysis of data.
resultsTwenty-two studies, conducted on the impact of vitamin D on fertility parameters for females, were recruited in the current study. Vitamin D supplementation showed a significant enhancement in several parameters, including vitamin D level, number of dominant follicles, Ovulation rate, and pregnancy rate (MD = -2.3295% CI [-3.07, -1.56], MD = 0.81 95% CI [0.27, 1.35], MD = 0.81 95% CI [0.17, 1.45], and MD = 0.64 95% CI [0.20, 1.07], respectively). On the other hand, there was no significant impact on AMH levels.
conclusionFindings of current studies indicate a beneficial impact of vitamin D therapy on fertility outcomes regarding the number of dominant follicles, ovulation rate, and pregnancy rate.
