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 4-amino-1,8-naphthalimide containing tetramethylpiperidine in N-position was synthesized. The prepared 1,8-naphthalimide was found to possess bright yellow-green fluorescence in a solid state, which could be switched-off in the presence of acid vapors and then switched-on after exposure on base vapors. The observed fluorescence quenching or enhancement, respectively, was more than 10-fold. This behavior was quite opposite to that of the similar 4-oxy-1,8-naphthalimide, in which a well-pronounced PET process operates. In addition, the observed fluorescence quenching was accompanied with color change from yellow to red. Based on these results, the reported 4-amino-1,8-naphthalimide was successfully applied as a reversible solid-state emissive chemosensing material for rapid detection of acid-base vapors for multiple usage.
