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
Petunia inflata possesses S-RNase-based self-incompatibility (SI), which prevents inbreeding and promotes outcrossing. Two polymorphic genes at the S-locus, S-RNase and P. inflata S-locus F-box (Pi SLF), determine the pistil and pollen specificity, respectively. To understand how the interactions between Pi SLF and S-RNase result in SI responses, we identified four Pi SLF-like (Pi SLFL) genes and used them, along with two previously identified Pi SLFLs, for comparative studies with Pi SLF(2). We examined the in vivo functions of three of these Pi SLFLs and found that none functions in SI. These three Pi SLFLs and two other Pi SLFs either failed to interact with S(3)-RNase (a non-self S-RNase for all of them) or interacted much more weakly than did Pi SLF(2) in vitro. We divided Pi SLF(2) into FD1 (for Functional Domain1), FD2, and FD3, each containing one of the Pi SLF-specific regions, and used truncated Pi SLF(2), chimeric proteins between Pi SLF(2) and one of the Pi SLFLs that did not interact with S(3)-RNase, and chimeric proteins between Pi SLF(1) and Pi SLF(2) to address the biochemical roles of these three domains. The results suggest that FD2, conserved among three allelic variants of Pi SLF, plays a major role in the strong interaction with S-RNase; additionally, FD1 and FD3 (each containing one of the two variable regions of Pi SLF) together negatively modulate this interaction, with a greater effect on interactions with self S-RNase than with non-self S-RNases. A model for how an allelic product of Pi SLF determines the fate of its self and non-self S-RNases in the pollen tube is presented.
