Oat phytochrome A mRNA degradation appears to occur via two distinct pathways.
Article in The Plant cell, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 papers.
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.
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
We have identified possible mechanisms for the degradation of oat phytochrome A (PHYA) mRNA. The majority of PHYA mRNA molecules appeared to be degraded prior to removal of the poly(A) tail, a pathway that differs from that reported for the degradation of other eukaryotic mRNAs. Polyadenylated PHYA mRNA contained a pattern of putative degradation products that is consistent with a 5'-->3' exoribonuclease, although the participation of a stochastic endoribonuclease cannot be excluded. The poly(A) tail of PHYA mRNA was heterogeneous in size and ranged from approximately 14 to 220 nucleotides. Early PHYA mRNA degradation events did not appear to involve site-specific endoribonucleases. Approximately 25% of the apparently full-length PHYA mRNA was poly(A) deficient. Oat H4 histone, beta-tubulin, and actin mRNA populations had lower amounts of apparently full-length mRNAs that were poly(A) deficient. Degradation of the poly(A)-deficient PHYA mRNA, a second pathway, appeared to be initiated by a 3'-->5' exoribonucleolytic removal of the poly(A) tail followed by both 5'-->3' and 3'-->5' exoribonuclease activities. Polysome-associated RNA contained putative PHYA mRNA degradation products and was a mixture of polyadenylated and deadenylated PHYA messages, suggesting that the two distinct degradation pathways are polysome associated.
