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
Point-of-care testing for sepsis refers to diagnostic technologies that rapidly and effectively detect sepsis using specific biomarkers. The development of thin-film electrodes (TFEs) for biosensing applications has been frequently reported in recent years. Notably, TFEs have been employed to develop biosensors for C-reactive protein (CRP), a key biomarker of sepsis. This study presents a straightforward and rapid method for fabricating TFEs on substrates using a shadow mask technique. The process employs commercially available polyvinyl chloride sticker film, serving as a disposable shadow mask, to create a three-electrode system (working electrode (WE), counter electrode (CE), and reference electrode (RE) on a poly-(methyl methacrylate) substrate. The sequential deposition of 20 nm of titanium (Ti) and 120 nm of gold (Au) formed the WE and CE, while the RE was fabricated by depositing titanium and silver (Ag). The fabricated TFEs were characterized by field emission scanning electron microscopy, atomic force microscopy, and energy-dispersive X-ray spectroscopy analyses, revealing notable differences in surface morphology and elemental composition. A specific aptamer for the CRP biomarker is immobilized on the surface of a TFE. The electrochemical biosensor demonstrated a linear range of 0.02-0.9 ng/mL and a limit of detection of 6.5 pg/mL, indicating high sensitivity for detecting the CRP biomarker.
