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

The main objective of this study is to introduce a strategy for the synthesis of a new hybrid sorbent. This sorbent is based on the combination of layered double hydroxide (LDH) and a porphyrin-based covalent organic framework (COF), which is called (LDH/COF) for the hollow fiber solid-phase microextraction method (HF-SPME). For this purpose, Cu-Al-LDH was synthesized and combined with the tetra (4-aminophenyl) porphyrin to obtain a Cu-Al-LDH/porphyrin-based COF nanocomposite. Then, the synthesized composite was accommodated in the pores of the hollow fiber. The resulting extraction device was used to extract Hexaflumuron and Teflubenzuron (as the model analytes), present in food samples. The linear dynamic ranges, limit of detections, and limit of quantifications were in the range of 0.2-500.0 µg L
