Serum BDNF, VEGF, and EGF Levels in Pregnant Women with Anxiety and Depression.

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
Antenatal anxiety and depression frequently co-occur, negatively affecting maternal and offspring outcomes, yet their biological correlates remain insufficiently characterized. This cross-sectional study examined associations between anxiety and depressive symptoms and serum concentrations of brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF), proteins implicated in pregnancy-related vascular adaptations whose dysregulation has been associated with placental dysfunction and negative perinatal outcomes. A total of 148 women with uncomplicated second- and third-trimester pregnancies were assessed using the Hamilton Anxiety Rating Scale and Hamilton Depression Rating Scale. Serum BDNF levels were quantified by enzyme-linked immunosorbent assay, whereas VEGF and EGF were measured using a multiplex bead-based immunoassay during late pregnancy. Based on scale scores, participants were classified as controls, women with anxiety without depressive symptoms, or women with anxiety and depressive symptoms. In the between-group comparisons, women with clinically significant anxiety exhibited higher BDNF and EGF levels than controls. Regression analyses indicated that anxiety severity was positively associated with BDNF, VEGF, and EGF levels (all
