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

OBJECTIVE AND

designThis prospective experimental study aims to investigate whether matrilin-2 is released from burn injury and induces post-burn inflammatory responses as an endogenous danger signal. SUBJECTS: Fifteen burn patients, 15 volunteers, 12 matrilin-2-deficient mice, 36 C57BL/6 mice and raw 264.7 cells.

methodsMatrilin-2 levels were detected by enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction. The inflammatory cytokines production in Matn2 deficient mice and wide type mice were detected by ELISA. Macrophages were activated by recombinant mouse MATN2 with or without adding anti-Toll-like receptor (TLR) 4 antibody. Student's t test and one-way analysis of variance were used for statistical analysis.

resultsThe matrilin-2 levels in serum of burned patients were drastically elevated as compared to those of healthy controls. The matrilin-2 levels in burned mice were significantly increased than those of non-burned controls, whereas the matrilin-2 mRNA expression was not significantly changed after burn. In addition, Matn2 deficient mice showed remarkably less inflammatory cytokines production and less neutrophil infiltration in lung. Exogenous MATN2 induced potent expression of proinflammatory cytokines production in macrophages, which was inhibited by anti-TLR4 antibody.

conclusionMatrilin-2 induces post-burn inflammatory responses as an endogenous danger signal, partly through a TLR4-mediated mechanism.
