1 · What the graph read from it

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.

2 · The registry

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

A flexible polyethylene terephthalate (PET) substrate was employed for the fabrication of a resistive-type humidity sensor using screen-printed polypyrrole (PPy)/CuO nanocomposite conductive inks. A series of conducting polymer-metal oxide composite-based sensors with varying compositions was prepared, and their humidity-sensing performances were systematically evaluated. The structural and morphological features of the composites were characterized using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The sensing behaviour of the printed devices was investigated over a relative humidity (RH) range 22–97% at room temperature, focusing on parameters such as relative resistance, sensitivity, dynamic response, and hysteresis. Enhanced sensitivity was achieved with the incorporation of CuO into PPy. The superior sensing performance is attributed to the combined structural characteristics and hydrophilic nature of CuO. The PPy/CuO nanocomposite with a 1:1 weight ratio, prepared via mechanical mixing and screen printing, exhibited the highest sensitivity over a broad humidity range (22–97% RH), along with fast response/recovery times (~ 50/60 s) and negligible hysteresis.
