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 outlines the optimised materials used to improve the output performance of a triboelectric nanogenerator based on the contact separation mode. The selection of materials plays a crucial role in enhancing the output voltage of the triboelectric nanogenerator. This study involves the design of three distinct triboelectric nanogenerator models using polytetrafluoroethylene (PTFE), polydimethylsiloxane (PDMS), and silicone. Numerical analysis is conducted using the finite element method in COMSOL Multiphysics software to determine the output performance of these models under externally applied pulse pressure. The output voltage profiles of each model are compared, and it is observed that the PTFE-based model consistently produces an output voltage of 26 V when subjected to a pulse pressure of 3 kPa. These devices are well-suited for use in healthcare monitors, human motion detection, and gesture monitoring because of their inherent self-powering capability.
