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

Noninvasive sampling of milk fat for isolation of RNA is an alternative technique to assess the mammary transcriptome. However, contamination of RNA from milk fat with nonmammary sources of RNA may complicate the interpretation of results. We measured transcript abundance of 8 genes in RNA from milk fat, milk somatic cells, mammary tissue, and blood leukocytes to determine how the transcript abundance of selected genes compares between RNA sources. Samples from 8 healthy cows were harvested immediately after slaughter. Blood was collected during exsanguination. Milk and mammary tissue were collected from the same mammary gland. Mammary tissue was frozen immediately, and fluids were centrifuged to collect the buffy coat from blood, and the fat layer and cell pellet from milk. The RNA isolated from all tissue sources was prepared for reverse-transcription quantitative PCR. Relative transcript abundance for each gene was determined by normalizing the abundance of the target gene against the abundance of reference genes (
