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 find an ideal biosurface to regenerate conjunctival epithelium.

designExperimental study.

methodsPieces of human cadaveric conjunctival epithelium removed of connective tissues were randomly placed on 8 different biosurfaces to grow primary conjunctival epithelial cells for 9 to 14 days until the fastest growing cultures covered 80% to 90% of the film surface. Main outcome measures were growth, proliferation capacity, startification, mucin 5AC (MUC5AC) secretion, and compositional balance in cell types.

resultsAll titanium-based films (titaminates) supported the growth, stratification, proliferation, and MUC5AC secretion function of human primary conjunctival epithelial cells (HCjECs), but none of the zinc-based films grew cells at all. Although HCjECs' ability to proliferate, stratify, and secrete MUC5AC per unit cell area was similar across all titaminates, titanium dioxide (TiO

conclusionsGiven the body-friendly nature and clinically proven safety and efficacy of titanium, titaminates TiO
