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

Necdin (Ndn) transgenic (Tg) mice were generated with a bacterial artificial chromosome (BAC) clone. Droplet digital PCR (ddPCR) and inverse PCR methods revealed that the transgene consisted of four fragments with a total length of 171 kb. Two of these fragments were tandem tail-to-tail duplicates of 77 kb and 37 kb that both contained a Ndn gene. The transgene was inserted in chromosome 15qD1. Ndn is a paternally expressed imprinted gene; however, the total expression level of Ndn in hemizygous Tg mice was approximately twofold higher than that in wild-type mice. ddPCR assays with locked nucleic acid (LNA) TaqMan probes revealed that transgenic Ndn expression was almost equal to endogenous Ndn expression, despite there being two copies of the Ndn gene in the transgene, indicating an interaction between the transcriptional regulation of endogenous Ndn and the transgene. ddPCR assays with LNA TaqMan probes were also applied for imprinting analysis to confirm exclusive paternal expression in tissues with low Ndn expression. This is the first report of a Tg mouse with a tandem duplication of a Ndn transgene and Ndn overexpression, which will be useful for the in vivo study of Ndn overexpression and for rescue experiments of the neonatal lethality seen in the Ndn knockout mouse.
