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

Aza-Diels-Alder cycloaddition reaction is a critical synthetic method for the production of bioactive tetrahydroquinolines. To this aim, an imine obtained from the reaction of an aniline derivative and a carbonyl compound is cyclized with an alkene in the presence of a catalyst. In this research, some tetrahydroquinoline compounds are synthesized through aza-Diels-Alder reaction in the presence of a prepared Ce(III) immobilized on the functionalized halloysite (Ce/Hal-TCT-IDA) as a catalyst. Ce/Hal-TCT-IDA was prepared by incorporation of aminopropyl silane on the halloysite surface, followed by treatment with 2,4,6-trichloro-1,3,5-triazine (TCT) and iminodiacetic acid (IDA), and loading cerium nitrate. Then, it was characterized and analyzed by different analytical methods, indicating the amorphous agglomerated grains (20-60 nm), containing 0.00196 mmol g
