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

purposeTo determine the efficacy of the superoxide dismutase mimetic, manganese(III) tetrakis(1-methyl-4-pyridyl) porphyrin (Mn-TM-2-PyP), in vitro in human corneal epithelial (HCE-T) cells and in vivo in a preclinical mouse model for dry-eye disease (DED).

methodsIn vitro, HCE-T cultures were exposed either to tert-butylhydroperoxide (tBHP) to generate oxidative stress or to hyperosmolar conditions modeling cellular stress during DED. Cells were pre-treated with Mn-TM-2-PyP or vehicle. Mn-TM-2-PyP permeability across stratified HCE-T cells was assayed. In vivo, Mn-TM-2-PyP (0.1% w/v in saline) was delivered topically as eye drops in a desiccating stress/scopolamine model for DED. Preclinical efficacy was compared to untreated, vehicle- and ophthalmic cyclosporine emulsion-treated mice.

resultsMn-TM-2-PyP protected HCE-T cells in a dose-dependent manner against tBHP-induced oxidative stress as determined by calculating the IC DISCUSSION: Our data suggest that Mn-TM-2-PyP, a prototypic synthetic metalloporphyrin compound with potent catalytic antioxidant activity, can improve signs of DED in vivo by reducing oxidative stress in corneal epithelial cells.
