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 series of pyrimidine derivatives were constructed by replacing hydrogen atoms with nitro groups. To explore their thermal stability and kinetic stability, heat of formation (HOF) and dissociation energies (BDE) are calculated based on the density functional theory with the B3PW91/6-311+G(d,p)//MP2/6-311+G(d,p) method. Based on our calculations, all derivatives are confirmed stable enough to be synthesized in laboratory. To explore the detonation characters, the detonation velocity and detonation pressure are calculated by using the empirical Kamlet-Jacobs equation and good detonation parameters were confirmed for most of title molecules. Based on our calculations, four molecules (2,4,5,6-tetranitropyrimidine, 4,5,6-trinitropyrimidine, 2,4,6-trinitropyrimidine, 2,4,5-trinitropyrimidine ) are screened out as potential high-energy-density materials for further research.
