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
Shake flasks are one of the most widely used cultivation vessels in biotechnological process development. To improve the process understanding, new technologies have been reported for online monitoring of different parameters like oxygen, pH, or biomass in the last couple of years. However, most reports address the monitoring of a single parameter per shake flask. This work evaluates the ability to measure dissolved oxygen (DO), biomass, and fluorescence in parallel with a new Multiparameter Sensor (MPS). Therefore, abiotic tests for reproducibility, sensitivity, and accuracy were performed. In biological tests, different microbial systems were used to evaluate if a wide range of applications is feasible. This work demonstrates that three different parameters: DO, biomass, and fluorescence can be monitored online, in parallel, for various biological systems. The online data obtained provide crucial process knowledge, such as the start of intracellular product formation. Abiotic and biological tests showed good reproducibility, resolution, and sensitivity to changing environmental conditions. Compared to other existing measurement systems for DO or oxygen transfer rate, similar or in the former case, more data points can be recorded, allowing a detailed overview and a better understanding of the process.
