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
Micro Electro Mechanical Systems (MEMS) based Capacitive Pressure Sensors (CPS) have shown their versatility and reliability in numerous applications. In this work, an innovative approach to optimize sensor performance through the integration of a novel wing-like mechanism is proposed. Unlike traditional CPS this mechanism employs two insulating layers attached to the upper layer of the substrate wing-like structure, which opens when pressure is applied, ultimately leading to the formation of a touch point. By decreasing the distance, the diaphragm must deflect before making contact, making it more responsive to applied pressure the sensor's sensitivity is greatly increased. Key performance metrics including capacitance variations, capacitive sensitivity and the deflection of diaphragm using small deflection theory have been analytically evaluated. To verify the analytical calculations of capacitance, capacitive sensitivity, and mechanical sensitivity MATLAB is used, while COMSOL Multiphysics is utilized to validate the diaphragm's deflection.
