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

Cinnamomum kanehirae Hayata and C. camphora (L.) Presl are important tree species in eastern Asia. The wood of C. kanehirae is in increasing demand for culturing Antrodia cinnamomea, a medicinal fungus that naturally grows inside the trunk of C. kanehirae. Putative hybrids between C. kanehirae and C. camphora were previously reported but with no scientific evidence, leading to confusion or misplanting. First, to identify the female parent of putative hybrids, the maternal inheritance InDel (insertion/deletion) markers were developed by using low-coverage sequencing. SNPs were developed by using genotyping-by-sequencing (GBS) approach in C. kanehirae, C. camphora and putative hybrids. The results indicated that the female parent of the studied hybrids was C. camphora. Eight hundred and forty of the 529,006 high-density SNPs were selected and used for analysis. Hybrids were classified as F1 (C. kanehirae × C. camphora), F2 and backcrosses. Hybridization has occurred in the human-developed area of eastern and southwestern Taiwan, and the introgression was bidirectional. For producing pure wood, buffering zones should be established around seed orchards to avoid cross-species pollination and to preserve the genetic purity of C. kanehirae. The DNA markers developed in this study will also be valuable for further wood identification, breeding and evolutionary research.
