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

purposeThe conjunctiva maintains the health of the ocular surface by protecting the eye from pathogen invasion, injury, and dryness. In this study, we investigated the regulation of hyaluronan (HA) synthesis by cytokines in conjunctiva-derived cells.

methodsCultured primary cells derived from human conjunctivas that had been removed as surgical specimens were transfected with an immortalizing gene (human papilloma virus 16 E6/E7). To compare the biological features of the primary and immortalized cells, we assessed their morphological features and gene expression patterns. We also examined the effects of inflammatory cytokines on hyaluronan synthase (HAS) expression and HA production.

resultsThree conjunctiva-derived cell strains were established and could be passaged up to 15 times. All strains expressed β2MG and KRT13 transcripts, highly expressed in conjunctival epithelial cells. HA production and expression of the three HAS isoforms were detected in the cell strains; however, cytokine treatment had no significant effect on HA production or HAS isoform expression.

conclusionsWe succeeded in deriving three human cell strains from conjunctival tissue. In the conjunctiva-derived cell strains, HA production and HAS mRNA expression were stable and were not changed by either TGF-β or PDGF-BB.
