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
Water-induced electrical responses were investigated using porous electrospun PAN-based composite membranes containing CNTs and CNCs. Following the injection of 20 μL of a 2 wt% NaCl solution, transient open-circuit voltage responses were observed from the PAN, PAN-CNT, and PAN-CNT-CNC devices, with maximum values of approximately 47, 42, and 68 mV, respectively, in the tested devices. Three successive injection-drying cycles demonstrated repeated transient responses within individual devices but did not establish device-to-device reproducibility or long-term stability. Raman and FTIR analyses supported the incorporation of CNTs and the modification of the water-interacting environment following CNC addition, respectively. The voltage waveform depended on the liquid type, NaCl concentration, and wetting-drying history, including a transient reverse-voltage response during drying. These results provide a proof-of-concept observation of wetting-drying-dependent electrical behavior in electrospun PAN-based porous membranes. Load-dependent power, long-term durability, and device-to-device reproducibility remain to be established.
