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

Non-syndromic amelogenesis imperfecta (AI) is a collection of isolated inherited enamel malformations that follow X-linked, autosomal-dominant, or autosomal-recessive patterns of inheritance. The AI phenotype is also found in syndromes. We hypothesized that whole-exome sequencing of AI probands showing simplex or recessive patterns of inheritance would identify causative mutations among the known candidate genes for AI. DNA samples obtained from 12 unrelated probands with AI were analyzed. Disease-causing mutations were identified in three of the probands: a novel single-nucleotide deletion in both KLK4 alleles (g.6930delG; c.245delG; p.Gly82Alafs*87) that shifted the reading frame, a novel missense transition mutation in both MMP20 alleles (g.15390A>G; c.611A>G; p.His204Arg) that substituted arginine for an invariant histidine known to coordinate a structural zinc ion, and a previously described nonsense transition mutation in a single allele of FAM83H (c.1379G>A; g.5663G>A; p.W460*). Erupted molars and cross-sections from unerupted parts of the mandibular incisors of Mmp20 null mice were characterized by scanning electron microscopy. Their enamel malformations closely correlated with the enamel defects displayed by the proband with the MMP20 mutation. We conclude that whole-exome sequencing is an effective means of identifying disease-causing mutations in kindreds with AI, and this technique should prove clinically useful for this purpose.
