1 · What the graph read from it

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.

2 · The registry

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 rising demand for natural products is accelerating research into sustainable methods for producing bio-based flavourings like ethyl butyrate. In this study, ethyl butyrate was successfully produced through the enzymatic esterification of butyric acid and ethanol, which were derived from the co-cultivation of Clostridium tyrobutyricum and Saccharomyces cerevisiae. Initial monoculture experiments with both strains were performed to investigate compromised fermentation conditions for co-cultivation. Based on these findings, anaerobic co-cultivation conditions were established at 37 °C and 150 rpm, with the pH controlled at 6. The effects of varying inoculation times in co-culture were examined, considering the solvent and acid tolerance of both strains. Due to the limited acid tolerance of S. cerevisiae, with significant inhibition at butyric acid concentrations above 10 g L¯
