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 current study investigates whether microRNA (miRNA) regulators of epithelial-mesenchymal transition (EMT), tissue fibrosis, and angiogenesis are differentially expressed in human primary pterygium. Genome-wide miRNA and mRNA expression profiling of paired pterygium and normal conjunctiva was performed in the context of conventional excision of pterygium with autotransplantation of conjunctiva (n = 8). Quantitative real time polymerase chain reaction (qRT-PCR) was used to validate the expression of key molecules previously detected by microarray. In pterygium, 25 miRNAs and 31 mRNAs were significantly differentially expressed by more than two-fold compared to normal conjunctiva. 14 miRNAs were up-regulated (miR-1246, -486, -451, -3172, -3175, -1308, -1972, -143, -211, -665, -1973, -18a, 143, and -663b), whereas 11 were down-regulated (miR-675, -200b-star, -200a-star, -29b, -200b, -210, -141, -31, -200a, -934, and -375). Unsupervised hierarchical cluster analysis demonstrated that members of the miR-200 family were coexpressed and down-regulated in pterygium. The molecular and cellular functions that were most significant to the miRNA data sets were cellular development, cellular growth and proliferation, and cellular movement. qRT-PCR confirmed the expression of 15 of the 16 genes tested and revealed that miR-429 was down-regulated by more than two-fold in pterygium. The concerted down-regulation of four members from both clusters of the miR-200 family (miR-200a/-200b/-429 and miR-200c/-141), which are known to regulate EMT, and up-regulation of the predicted target and mesenchymal marker fibronectin (FN1), suggest that EMT could potentially play a role in the pathogenesis of pterygium and might constitute promising new targets for therapeutic intervention in pterygium.
