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 work describes the use of a series of Lewis acids supported in different ionic liquids (ILs), based on an imidazolium cation, as catalysts for the cationic polymerization of styrene. The influence of these ILs, the effect of Lewis acids, temperature, catalyst concentration, and the presence of organic solvents were investigated to evaluate the best conditions for polymerization. These catalytic systems were effective to polymerize styrene in the temperature range of 50-90 °C, obtaining quantitative conversions in the presence of ILs in polymerization catalyzed by small amounts of Lewis acid. It was possible to synthesize polymers with wide ranges of number-average molar mass, in the range of 200,000-600 g mol
