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

Drug repositioning promises the advantages of reducing costs and expediting approvalschedules. An induction of the anesthetic and sedative drug; midazolam (MDZ), regulatesinhibitory neurotransmitters in the vertebrate nervous system. In this study we show the potentialfor drug repositioning of MDZ for dentin regeneration. A porcine dental pulp-derived cell line(PPU-7) that we established was cultured in MDZ-only, the combination of MDZ with bonemorphogenetic protein 2, and the combination of MDZ with transforming growth factor-beta 1. Thedifferentiation of PPU-7 into odontoblasts was investigated at the cell biological and genetic level.Mineralized nodules formed in PPU-7 were characterized at the protein and crystal engineeringlevels. The MDZ-only treatment enhanced the alkaline phosphatase activity and mRNA levels ofodontoblast differentiation marker genes, and precipitated nodule formation containing a dentinspecificprotein (dentin phosphoprotein). The nodules consisted of randomly orientedhydroxyapatite nanorods and nanoparticles. The morphology, orientation, and chemicalcomposition of the hydroxyapatite crystals were similar to those of hydroxyapatite that hadtransformed from amorphous calcium phosphate nanoparticles, as well as the hydroxyapatite inhuman molar dentin. Our investigation showed that a combination of MDZ and PPU-7 cellspossesses high potential of drug repositioning for dentin regeneration.
