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
The psychrotolerant yeast Guehomyces pullulans 17-1 grows the best at 15 °C. When the yeast cells grown at 15 °C for 48 h were transferred to new medium and grown at 10, 15, and 25 °C, respectively, trehalose-6-phosphate synthase (Tps1) activity and trehalose content of the yeast cells grown at 25 °C were higher than those of the yeast cells grown at 10 and 15 °C. However, Tps1 activity and trehalose content of the yeast cells grown at 10 °C were lower than those of the yeast cells grown at 15 °C. This may suggest that trehalose synthesized by G. pullulans 17-1 only can play more important role in its adaption to high temperature than in its adaption to low temperature. After the GPTPS1 gene encoding trehalose-6-phosphate synthase was cloned from the psychrotolerant yeast, it was found that the promoter of the gene contained several stress-response elements such as C4T and AG4, indicating that the gene expression might be regulated by heat shock. It was also found that the transcriptional level of the GPTPS1 gene in the yeast cells grown at 25 °C was higher than that of the GPTPS1 gene in the yeast cells grown at 10 and 15 °C. However, the transcriptional level of the GPTPS1 gene in the yeast cells grown at 10 °C was lower than that of the yeast cells grown at 15 °C. This meant that expression of the GPTPS1 gene was constant with the changes in Tps1 activity and trehalose content of the yeast cells.
