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

The amelogenin proteins are required for normal enamel development, and the most abundant amelogenins expressed from alternatively spliced mRNAs are M180 and leucine-rich amelogenin protein (LRAP). The X-Chromosomal Amelogenin (Amelx) null [knockout (KO)] mouse has an enamel defect similar to human X-linked amelogenesis imperfecta. The disorganized enamel layer in KO mice is 10-20% of the thickness of wild-type (WT) enamel and lacks prismatic structures. When the KO mice were mated with mice that express the transgene M180-87, (TgM180-87) partial rescue of the phenotype was observed such that enamel thickness, volume, and density increased. A second transgene was introduced by mating TgM180 KO mice with TgLRAP mice, and male offspring were characterized for genotype and tooth phenotype was evaluated by scanning electron microscopy. The molar enamel thickness of TgM180-LRAP KO mice was further increased, and the structure was improved, with a more defined decussation pattern compared with singly rescued mice. We conclude that TgM180 provides significant rescue of the KO phenotype. Although the effectiveness of the LRAP transgene, alone, to rescue is less obvious, the addition of the LRAP transgene to the M180 transgene in KO enamel leads to an added improvement in both amount and structure and thus these transgenes function in a complementary manner. Together, the two most abundant amelogenins lead to the formation of obvious enamel decussation patterns.
