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

The changes in gene expression during senescence are very interesting. Early population doubling cDNA-1 (EPC-1, also known as pigment epithelial derived factor, PEDF) is one of the genes whose expression decreases dramatically during cellular aging. We examined whether or not EPC-1/PEDF promoter activity was affected by the cellular ageing using human diploid lung fibroblast cells in culture. Here we showed the promoter/enhancer region of EPC-1/PEDF existed at more than 1760 bp upstream from the transcriptional initiation site of the gene, and was regulated by both aging and cell cycle. These findings suggest that the expression of the EPC-1/PEDF gene is, at least in part, regulated transcriptionally in the cells. The analysis of the promoter region of the EPC-1/PEDF gene in this paper suggests the age- and cell cycle-dependent expression of specific transcriptional factor(s).
