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
Bokashi fertilizer, an organic fertilizer made of plant residue, has been used in Japan not only to fertilize plants but to regulate their growth. Lactic acid bacteria have been found to play an important role in the fermentation process of Bokashi, but the relationship between these bacteria and plant growth activity has not been clarified. Using the adzuki rooting assay, this study identified 3-phenyllactic acid (PLA) produced by lactic acid bacteria as a root promoting compound in Bokashi. PLA showed synergistic effect with tryptophan, but no stem elongation activity. Lactic acid bacteria produced equal quantities of the L- and D-forms of PLA, which have similar root promoting activity. PLA did not significantly affect the amount of endogenous indole-3-acetic acid (IAA), although the chemical structure of PLA is highly similar to that of L-2-aminooxy-3-phenypropionic acid (L-AOPP), which inhibits IAA biosynthesis. These results indicate that the root promoting activity of PLA is not simply due to its increase in the amount of active auxin.
