1 · What the graph read from it

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.

2 · The registry

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: Over the past few decades, a marked decline in human semen quality has been observed, with evidence suggesting that dietary factors may account for 50-60% of this decline. The present randomized clinical trial aimed to evaluate the effects of a fertility diet (FD) on sperm parameters in infertile men. Materials and Methods: In this randomized clinical trial study, 70 infertile men were randomly assigned to two groups: the intervention group, which followed the FD plan, and the control group, which kept a healthy diet (HD) for 12 weeks. Anthropometric measurements, semen analysis, DNA fragmentation index (DFI), malondialdehyde (MDA) levels, and sex hormone profiles were assessed before and after the intervention. Dietary intake was monitored throughout the study. Results: Compared to the HD group, the FD group showed significant improvements in total sperm count (P=0.016), sperm concentration (P=0.003), total motility (P=0.024), progressive motility (P=0.048), and normal morphology (P=0.023). Participants in the FD group showed an increase in the intake of total fat, monounsaturated fatty acids, polyunsaturated fatty acids, omega-3 fatty acids and fiber during the intervention (P<0.05). Additionally, the FD group consumed higher amounts of key fertility-related micronutrients including magnesium, calcium, phosphorous, potassium, zinc, selenium, vitamin C, and lycopene. Notably, a significant reduction in DFI (P=0.010) and MDA (P<0.001) was also observed in the FD group compared to the HD group. No significant differences were found in sex hormone levels or anthropometric parameters between the groups. Conclusion: These findings suggest the potential of a FD to improve sperm parameters and reduce DFI and oxidative stress. However, further studies with larger sample sizes and longer durations are needed to confirm these effects (registration number: IRCT20230514058181N1).
