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

The aim of this work was to study the dielectric properties of dot capacitors composed of a microtip coated with a thin layer of epoxy resin bonded to a steel plate. Two microtips with radii ranging from 3 to 5 μm were fabricated via electrochemical etching and coated with an epoxy layer 27-35 μm in thickness. The microtips were characterized by scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS). This study showed that composite cold-field emission emitters behave as dot capacitors. The real and imaginary parts of the impedance and permittivity, along with the direct and alternating conductivities, activation energies, and hopping energies, were examined. These evaluations were conducted at temperatures of 30, 45, 60, 75, and 90 °C, with a frequency range of 1 to 10
