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
This study investigates the performance and stability of extended-gate field-effect transistor (EGFET) pH sensors with three different reference electrode configurations: conventional external Ag/AgCl, external gold (Au), and integrated Au electrodes. The goal is to identify an optimal reference electrode configuration for enhancing the portability and manufacturability of EGFET pH sensors, which are crucial in medical, agricultural, and environmental applications. Results showed that the integrated Au electrode exhibits superior stability and comparable sensitivity to those of Ag/AgCl and external Au electrodes. The integrated Au electrode configuration achieved a 96 mV/pH sensitivity with 97% linearity across a pH range of 4 to 10. Stability tests revealed that the integrated Au electrode had the least drift under different pH conditions compared with the other two configurations, suggesting improved reliability. These findings highlight the integrated Au electrode's potential as a viable alternative to conventional reference electrodes in EGFET pH sensors, offering enhanced performance and practicality for point-of-care testing and other applications.
