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

This study represents the development of an innovative solid-phase microextraction (SPME) adsorbent based on the in situ electro-polymerized polyaniline on the carbon fiber felt (PANI@CFF). The combination of PANI and CFF resulted in a synergistic enhancement of adsorption capacity, creating a novel thin film SPME adsorbent. The adsorbent was characterized using FTIR, FE-SEM, XRD, and EDX techniques. The resulting 3D adsorbent represented high porosity, chemical stability in organic solvents, easy modification, and simple operation, making it an efficient platform for preconcentration applications. The PANI@CFF was utilized to efficiently extract non-steroidal anti-inflammatory drugs (NSAIDs), demonstrating exceptional performance due to its unique structural properties and multifunctional groups. All of the key extraction parameters were optimized using a one-variable-at-a-time approach. The developed SPME combined with HPLC-UV offered a wide linear range (0.05-1000 µg L⁻
