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
Inspired by the signal amplification property of the field-effect transistor (FET) enabled by electric field modulation across the conducting channel, a carbon-based FET hydrogen sulfide (H2S) sensor with ionogel sensing material was fabricated, providing trace-level detection without the need of thermal or optical fields. Under an applied back-gate voltage, the working state of the FET sensor could be regulated to the linear region, significantly boosting the sensor’s sensitivity toward low-concentration analytes. The proposed sensor exhibited a room-temperature detection ability toward 0.1-1 ppm of H2S. Leveraging the hydrophobic nature of the ionogel, the sensor showed a slight response variation (6.8%) toward 1 ppm of H2S in the range 10–90% relative humidity (RH). This work provides an electric field modulation strategy for trace-level gas detection, offering a feasible solution for the chip-integrated development of gas sensors.
