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
In brief: Generalized anxiety disorder, major depressive disorder and their treatment selective serotonin reuptake inhibitors (SSRIs) impact 4-17% of pregnancies worldwide and alter the epigenome of numerous tissues, but their effects on the ovarian follicle are unknown. This study profiles the methylome of granulosa cells, revealing novel epigenetic pathways and molecular mechanisms altered by mental health conditions and their treatments. Abstract: Generalized anxiety and major depressive disorders (GAD/MDD) impact 4-17% of pregnancies worldwide. GAD/MDD and SSRIs alter the epigenome of numerous tissues; however, their effect on the ovarian follicular niche is unknown. In this study, we determined SSRI concentrations in the follicular fluid and matched patients by clinical and stimulation characteristics, and then grouped them into three groups: i) treated GAD/MDD (n = 10), ii) untreated GAD/MDD (n = 4), and iii) control (n = 10). DNA methylation sequencing was performed on granulosa cells using the Illumina TruSeq Methyl Capture EPIC kit. For patients with untreated GAD/MDD, we identified 3,829 differentially methylated sites (DMSs). Pathway analysis revealed an enrichment in genes involved in catabolism and immune response for the hypomethylated DMSs and hypermethylated DMSs were associated with protein localization and cellular transport. When assessing the effect of SSRI treatment, we identified 3,690 DMSs. Hypomethylated DMSs were associated with genes involved in cytoskeleton organization and cellular transport, whereas hypermethylated DMSs were associated with apoptosis and cell cycle. This is the first study profiling the methylome of human granulosa cells from patients with treated or untreated GAD/MDD. This study provides a valuable dataset describing the effects of SSRI on cells in the ovarian follicular niche.
