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

background

methodsThe plastid genome DNA was extracted from both fern species and then sequenced on the Illumina Hiseq 4000. Sequences were assembled into contigs by SOAPdenovo2.04, aligned to the reference genome using BLAST, and then manually corrected. Genome annotation was performed by the online DOGMA tool. General characteristics of the plastid genomes of the two species were analyzed and compared with closely related species. Additionally, phylogenetical trees were reconstructed by maximum likelihood methods. The content of dryocrassin of the two species were determined according to the Standards of Chinese Herbal Medicines in Hong Kong.
