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

Purpose: Dry eye disease (DED) is a multifactorial disease associated with ocular surface inflammation. Toll-like receptors (TLRs) are integral in the initiation of inflammatory signaling. Therefore, we evaluated the effect of TLR-deficiency on dry eye-related ocular surface damage and inflammation using a mouse model of experimental dry eye (EDE). Methods: C57BL/6 wild-type (WT), MyD88-/-, and IL-1R-/- mice were exposed to EDE conditions for 5 days. Tear production was measured by phenol red thread test and ocular surface damage assessed with fluorescein staining. Corneal homogenates were obtained for matrix metalloproteinase (MMP) and cytokine expression analysis by Luminex assay and quantitative PCR. In addition, whole eyes and eyelids were dissected and goblet cells and Meibomian glands were imaged, respectively. Results: Following 5 days of EDE, WT mice had extensive ocular surface staining, while MyD88-/- mice had no increased staining above non-EDE conditions. Similarly, MyD88-/- mice did not have increased corneal MMP-2, 3, or 8 concentrations, as seen with WT mice. MyD88-deficiency also resulted in decreased corneal cytokine levels. In addition, MyD88-/- mice had significantly lower conjunctival goblet cell counts compared with both WT (EDE) and IL-1R-/- (non-EDE) mice. However, there was no difference in Meibomian gland morphology between WT, IL-1R-/-, and MyD88-/- mice. Conclusions: These studies demonstrate the importance of TLR signaling in dry eye development. Mice lacking TLR signaling, MyD88-/-, were protected from EDE-induced ocular surface damage and inflammatory mediator expression, warranting further investigation into TLR inhibition as a potential therapeutic for DED.
