Mitigating the deleterious impact of saliva on cell-free expression sensors for point-of-use diagnostics.

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
Point-of-use sensors that detect biomarkers in noninvasive biofluids, such as saliva, could provide individuals with valuable insights into their health and performance status at home or in the field. Cell-free biosensors have the potential to meet these requirements, as these sensors can detect a wide variety of analytes and can be stored at room temperature after freeze-drying. However, saliva inhibits the function of cell-free biosensors, in part due to the presence of interfering proteins and nucleases. Here we show simple strategies to mitigate the inhibitory effects of saliva on the function of cell-free expression systems, including the use of nuclease inhibitors and pretreatment of saliva with centrifugal filtration or heat. We also show successful implementation of our mitigation strategies to detect cortisol spiked into pooled human saliva using a cell-free biosensor. Combined, our results show that simple approaches can be used to enable the function of cell-free biosensors in saliva.
