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 of solid tumor depends on angiogenesis, a process regulated by the balance of pro- and anti-angiogenic factors. We investigated the expression of anti-angiogenic factor pigment epithelium-derived factor (PEDF) and proangiogenic factors vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) with immunohistochemistry in 64 bladder tumor samples and 23 normal controls. Compared with normal urothelium, we identified decreased PEDF expression (P = 0.000) whereas increased expression of VEGF (P = 0.000) and MMP-9 (P = 0.000) in tumorous tissue as well as in papillary urothelial neoplasm of low malignant potential (PUNLMP) (P = 0.009 and P = 0.000 accordingly) but MMP-9 (P = 0.704). Decreased PEDF expression was revealed with higher tumor grade (P = 0.014) but stage (P = 0.687). There was no age or gender preference in PEDF, VEGF or MMP-9 expression. Negative correlation of expression in tumorous and cancerous tissue regarding PEDF and VEGF (P = 0.000, r = -0.56, and P = 0.000, r = -0.50, respectively), PEDF and MMP-9 (P = 0.002, r = -0.39, and P = 0.032, r = -0.30, respectively) was identified. There was a negative correlation of expression between PEDF and VEGF (P = 0.016, r = -0.677) and no correlation between PEDF and MMP-9 (P = 0.147, r = -0.45) in PUNLMP. Decreased PEDF and increased VEGF and MMP-9 expression may play considerable roles in differentiation and invasion of bladder tumor.
