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

Growth factors can facilitate hippocampus-based learning and memory and are potential targets for treatment of cognitive dysfunction via their neuroprotective and neurorestorative effects. Dementia is common in Parkinson's disease (PD), but treatment options are limited. We aimed to determine if levels of growth factors are altered in the hippocampus of patients with PD, and if such alterations are associated with PD pathology. Enzyme-linked immunosorbent assays were used to quantify seven growth factors in fresh frozen hippocampus from 10 PD and nine age-matched control brains. Western blotting and immunohistochemistry were used to explore cellular and inflammatory changes that may be associated with growth factor alterations. In the PD hippocampus, protein levels of glial cell line-derived neurotrophic factor were significantly decreased, despite no evidence of neuronal loss. In contrast, protein levels of fibroblast growth factor 2 and cerebral dopamine neurotrophic factor were significantly increased in PD compared to controls. Levels of the growth factors epidermal growth factor, heparin-binding epidermal growth factor, brain-derived neurotrophic factor and mesencephalic astrocyte-derived neurotrophic factor did not differ between groups. Our data demonstrate changes in specific growth factors in the hippocampus of the PD brain, which potentially represent targets for modification to help attenuate cognitive decline in PD. These data also suggest that multiple growth factors and direction of change needs to be considered when approaching growth factors as a potential treatment for cognitive decline.
