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

PRIM2, encoding a subunit of primase involved in DNA replication and transcription, is expressed in the placenta and is crucial for mammalian development and growth. Its role in placental function is not well understood. Recently, PRIM2 was reported as imprinted in human white blood cells (WBC). We report here our failure to confirm imprinting of the PRIM2 locus in human placenta or WBC. The discordance between our results and those of others are likely due to an incorrectly annotated PRIM2 pseudogene found in the human genome database.
