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

Tetracycline (TC) is a broad-spectrum antibiotic primarily used for the prevention and treatment of bacterial infections in humans and animals. However, excessive use of tetracycline can lead to accumulation in the body, posing risks to human health. In this study, nitrogen-doped fluorescent carbon quantum dots (N-CQDs) were synthesized using sucrose as the carbon source and ethylenediamine as the nitrogen source via a microwave method. N-CQDs were characterized using transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), and ultraviolet-visible spectroscopy (UV-vis). The preparation conditions for N-CQDs were optimized, and the results showed that when glycerol was used as the solvent, the mass ratio of sucrose to ethylenediamine was 1:4, and the microwave power was 800 W, the fluorescence quantum yield of the synthesized N-CQDs reached 43.78%. Optimisation of the TC detection process indicated that at a reaction temperature of 50 °C, a reaction time of 20 min, and a buffer solution pH of 7, within a concentration range of 1.6 to 45 µmol/L, the linear regression equation for TC concentration versus N-CQDs fluorescence quenching degree is (F
