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

objectiveBrain-derived neurotrophic factor (BDNF), vascular endothelial growth factor (VEGF) and leptin have been hypothesized to be involved in the neurobiology of depression. The aim of this study was to investigate BDNF, VEGF and leptin levels in patients with severe melancholic depression.

methodsA total of 40 drug-free patients with major depressive disorder (MDD) with melancholic features and 40 healthy controls were included in the study. Demographic information, psychiatric evaluation and physical examination were documented for both groups. Serum BDNF, VEGF levels were determined by enzyme-linked immunosorbent assay and leptin with radioimmunoassay methods. The Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale were applied to the patients.

resultsThere were no significant differences in serum BDNF, VEGF and leptin levels between the patient and control groups. There was a negative correlation between BDNF levels and the number of depressive episodes. It was noted that VEGF levels decreased with increasing severity of depression.

conclusionsThese findings suggest that BDNF levels might be associated with the recurrence of depression and VEGF levels might be a determinant of the severity of depression.
