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

Advances in RNA-sequencing methods have uncovered many aspects of RNA metabolism but are limited to surveying either the 3' or 5' terminus of RNAs, thus missing mechanistic aspects that could be revealed if both ends were captured. We developed Akron sequencing (Akron-seq), a method that captures in parallel the native 5' ends of uncapped, polyadenylated mRNAs and 3' ends of capped mRNAs from the same input RNA. Thus, Akron-seq uniquely enables assessment of full-length and truncated mRNAs at single-nucleotide resolution. Akron-seq involves RNA isolation, depletion of ribosomal and abundant small capped RNAs, and selection of capped and polyadenylated mRNAs. The endogenous ends of mRNAs are marked by adaptor ligation, followed by fragmentation, cDNA generation, PCR amplification, and deep sequencing. The step-by-step protocol we describe here is optimized for cultured human cells but can be adapted to primary cells and tissues. Akron-seq can be completed within 6 d, and sequencing and analysis can be completed within 6 d.
