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
Background: Micronutrients such as vitamin B12 and D have recently gained attention for their potential roles in male reproductive health. Despite their significance, there's a critical gap in understanding their association with male infertility, particularly concerning suboptimal semen parameters. This study aimed to address this knowledge gap by examining serum vitamin B12 and D levels in infertile males, providing insights that could inform targeted interventions for couples facing male infertility challenges. Methods: This cross-sectional study, conducted at Tertiary Health care centre in north India for 2 years, enrolled 73 infertile males aged 20-40 years from the fertility clinic (participants exhibited suboptimal semen parameters). Clinical and demographic data were collected through interviews and record reviews, while semen samples underwent meticulous processing for the analysis of various parameters. Blood samples were collected after overnight fasting for serum vitamin B12 (ELISA) and vitamin D (CLIA) assessment. Statistical analyses, performed using SPSS, included t-tests, Chi-square tests, and Pearson's correlation analyses to explore associations between serum vitamin levels and semen parameters, with a significance level set at Results: The study comprised 73 infertile males with suboptimal semen parameters. Serum vitamin B12 levels (mean ± SD: 243.4 ± 69.3 pg/mL) and vitamin D levels (22.5 ± 13.2 ng/mL) were measured. Low vitamin B12 (<200 pg/mL) was observed in 29 participants (39.7%), while low vitamin D (<20 ng/mL) was noted in 51 participants (69.9%). Semen parameters revealed significant differences in sperm count, motility, and morphology between low and normal vitamin B12 groups. Similar patterns were observed with vitamin D levels, emphasizing potential associations between vitamin status and semen quality. Conclusion: Our findings suggest a potential link between low serum vitamin B12 and D levels and suboptimal semen parameters in infertile males. Addressing these nutritional deficiencies may hold promise for improving male fertility outcomes. Further research is warranted to elucidate the mechanisms involved and explore targeted interventions.
