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
Oxygen acts as the electron acceptor to oxidize ethanol by acetic acid bacteria during acetic acid fermentation. In this study, the energy release rate from ethanol and glucose under different aerate rate were compared, and the relationship between energy metabolism and acetic acid fermentation was analyzed. The results imply that proper oxygen supply can maintain the reasonable energy metabolism and cell tolerance to improve the acetic acid fermentation. Further, the transcriptions of genes that involve in the ethanol oxidation, TCA cycle, ATP synthesis and tolerance protein expression were analyzed to outline the effect of oxygen supply on cell metabolism of Acetobacter pasteurianus. Under the direction of energy metabolism framework a rational two-stage oxygen supply strategy was established to release the power consumption and substrates volatilization during acetic acid fermentation. As a result, the acetic acid production rate of 1.86 g/L/h was obtained, which were 20.78% higher than that of 0.1 vvm one-stage aerate rate. And the final acetic acid concentration and the stoichiometric yield were 88.5 g/L and 94.1%, respectively, which were 84.6 g/L and 89.5% for 0.15 vvm one-stage aerate rate.
