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 sense of smell relies on the monoallelic and monogenic expression of odorant receptor (OR) genes. Noncoding RNAs (RNAs that are not translated into proteins) may potentially be involved in the regulation of OR gene expression, but their roles in olfactory tissues remain elusive. Here we describe a protocol for isolating nuclear and cytoplasmic RNA fractions from mouse olfactory epithelium. The dissected tissue is subjected to cellular fractionation and RNA is extracted from the nuclear and cytoplasmic fractions. The purified RNA is then subjected to RT-PCR analysis, to verify the enrichment of nuclear/cytoplasm transcripts and control the quality of the fractionation. Determination of the subcellular localization of different RNAs may contribute to the identification of RNAs with regulatory functions in olfaction.
