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

backgroundQuantitative real-time reverse transcription PCR (qRT-PCR) requires a stable internal control to avoid misinterpretation of data or errors for gene expression normalization. However, there are still no validated reference genes for stable internal control in Poria cocos (Schw.) Wolf (Fuling). This study aims to validate the reference genes of P. cocos.

methodsThis study firstly collected the 14 candidate reference genes by BLASTP from the genome of P. cocos for qRT-PCR analysis to determine the expression levels of 14 housekeeping genes (GAPDH, MAPK, β-Act, RPB2, RPB1-1, RPB1-2, his3-1, his3-2, APT, SAMDC, RP, β-Tub, EIF, and CYP) under different temperatures and in response to different plant hormones (indole-3-acetic acid, abscisic acid, 6-benzylaminopurine, methyl jasmonate, and gibberellic acid), and the threshold cycle (Ct) values. The results were analyzed by four programs (i.e., geNorm, NormFinder, BestKeeper, and RefFinder) for evaluating the candidate reference genes.

resultsSAMDC, his3-2, RP, RPB2, and his3-1 were recommended as reference genes for treating P. cocos with indole-3-acetic acid, abscisic acid, 6-benzylaminopurine, methyl jasmonate, and gibberellic acid, respectively. Under different temperatures RPB2 was the most stable reference gene. CYP was the most stable gene for all 90 samples by RefFinder.

conclusionSAMDC, his3-2, RP, RPB2, and his3-1 were evaluated to be suitable reference genes for P. cocos following different treatments. RPB2 was the most stable reference gene under different temperatures and CYP was the most stable gene in the mycelia under all six evaluated conditions.
