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

objectiveThe purpose of this study was to determine the role of Ureaplasma urealyticum-derived lipid-associated membrane proteins (LAMPs) in the host innate immune system, specifically their effect on Toll-like receptors (TLRs).

methodsLAMPs were derived from U. urealyticum strains, and human amniotic epithelial cells (HAECs) were isolated from healthy full-term placentas. Cytokine concentrations were determined by enzyme-linked immunosorbent assay (ELISA) and TLR2 mRNA by real-time PCR. Expression of TLR2 was confirmed by Western blotting and immunohistochemistry.

resultsLAMPs induced HAECs to produce inflammatory cytokines interleukin (IL)-6, IL-8, and tumor necrosis factor (TNF)-α. Cytokine production was reduced after blocking TLR2 using TLR2 inhibitor (anti-hTLR2-IgA).

conclusionsLAMPs isolated from U. urealyticum induced TLR2-dependent up-regulation of inflammatory genes and cytokines in HAECs.
