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
Herein, we describe a simple and effective method of fabricating a porous thin silver (Ag) layer, exhibiting an excellent electromagnetic interference (EMI) shielding performance. The porous sintered Ag layer was fabricated by a simple blade-coating method using Ag nanoparticle (NP) dispersions. As-coated Ag NPs layer was sintered at a low temperature under 180 °C without external pressure to prevent device failure due to excessive pressure or thermal energy. The pressurelessly sintered Ag layer possessed an inherent porous structure, which multiplied the internal reflection of the incident electromagnetic (EM) waves within the Ag layer. The porous sintered Ag layer exhibited a high average EMI shielding efficiency (SE) of 56.5 dB over a broad frequency range of 0.5-18 GHz, which means EM waves were blocked over 99.99%. The EMI shielding performance of the porous sintered Ag layer was superior to that of previously reported EMI shielding materials. The practical application was demonstrated by near-field SE mapping of the porous sintered Ag layer coated PCB antennas. This research suggests a suitable and alternative EMI shielding method to replace package-level EMI shielding materials for a wide range of applications.
