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

3D printing enables low-cost, high-performance electrochemical sensors for bioanalytical and clinical use. Herein, we report, for the first time, a graphite/polylactic acid (G/PLA) conductive composite modified with a coumarin-benzothiazole derivative for 3D-printed electrodes targeting enhanced serotonin detection. The optimized composition (G/coumarin-benzothiazole/PLA, 35:5:60 wt %) was processed with a 3D pen to produce conductive electrodes without electrochemical activation. Electrochemical impedance spectroscopy showed an ≈74% decrease in charge-transfer resistance for the modified material, while cyclic voltammetry revealed an ≈137% increase in serotonin oxidation current and a distinct oxidation peak at +0.375 V vs Ag|AgCl|KCl
