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
In recent years, extensive studies have been devoted to the applications of surface-enhanced Raman spectroscopy (SERS) in detecting and identifying trace amounts of various analytes. The crucial issue for SERS applications is the selection of reliable and reproducible substrates. Therefore, most studies were dedicated to their fabrication, characterization, and evaluation using selected test compounds. This article reports the results of comparative studies on the fabrication, characterization, and evaluation of SERS substrates in the form of monolayers of amino acid-synthesized gold nanoparticles (AuNPs) on silicon and glass platforms. The combination of AuNPs synthesized with five amino acids and four platforms with smooth and rough surfaces yielded 17 potential SERS substrates. SERS substrates and their components were characterized using microscopy and spectroscopy techniques. The SERS performance of fabricated substrates was evaluated using
