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 magnetic covalent organic framework (Fe3O4@COF-TAPB-TPA) was designed and synthesized via a mild approach for the magnetic solid-phase extraction (MSPE) of polycyclic aromatic hydrocarbons (PAHs) coupled with HPLC analysis. Density functional theory (DFT) calculations were performed to elucidate the adsorption mechanism, revealing that van der Waals forces and π–π stacking interactions are the primary driving forces, complemented by hydrogen bonding. Following optimization of key parameters (adsorbent dosage, eluent type, pH, ionic strength, and adsorption time), the developed method demonstrated excellent analytical performance, including wide linear ranges (R2 ≥ 0.991), low limits of detection (0.021–0.098 µg L− 1) and quantification (0.068–0.517 µg L− 1), and satisfactory recoveries (57.52%–119.34%). The practical applicability of the method was validated through successful analysis of PAHs in water, milk, honey, and green tea beverages, highlighting its potential for routine monitoring in complex food matrices.
