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 evaluate the effect of topically administrated ripasudil, a rho kinase inhibitor, on blood flow in the optic nerve head (ONH) of normal rats.

methodsRipasudil (0.4%) or placebo was administered in the right eye of normal Brown Norway rats in a double-blind manner. Laser speckle flowgraphy was measured in the ONH of the right eye 20 or 40 min after a single instillation and before and after 7 or 14 days of twice daily instillation. Mean blur rate was evaluated in the total area (MA), the vessel region (MV), and the tissue region (MT). Intraocular pressure (IOP), blood pressure, ocular perfusion pressure (OPP), and heart rate were also recorded at each time point.

resultsAfter a single instillation, MV was significantly larger at 40 min than 20 min in the ripasudil group (P = 0.044) and was significantly lower in the placebo group (P = 0.023). MA and MV 40 min after instillation were significantly larger in the ripasudil group than in the placebo group (P = 0.022 and P = 0.006, respectively). After continuous instillation, MA and MV in the ripasudil group significantly increased from baseline after 7 and 14 days of treatment (both P < 0.05) and MA, MV, and MT were significantly higher than in the placebo group (MA: 7 and 14 days, P < 0.01; MV: 7 days, P = 0.003, and 14 days, P = 0.012; MT: 7 days, P = 0.046). There were no significant changes in IOP, blood pressure, or OPP after single or continuous instillation.

conclusionsTopical instillation of ripasudil increased blood flow around the ONH in the eyes of normal rats.
