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 laser-pyrolyzed cork-based electrochemical sensor is proposed for the determination of sodium nitrite, a widely used food additive that poses potential health risks. The pyrolysis parameters were varied individually, and electrochemical performance was compared to select the conditions that provided the highest conductivity and sensitivity. Additionally, a chemical treatment with a waterproofing spray was applied to enhance sensor stability and ensure reproducible measurements. The proposed sensor was characterized by scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (EDS), attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR), Raman spectroscopy, X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The performance of the sensor was evaluated for sodium nitrite detection in different beverage samples, including wine, orange juice, and mineral water. The results demonstrated a linear response range from 300 to 1000 μmol L⁻
