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

Benzene ring puckering generally arises from the strong repulsion between bulky substituents, while in this study, we present that benzene ring puckering can be achieved by repulsion between small substituents (nitro and methyl groups) facilitated by hydrogen-bonding attraction, as exemplified in 1,3,5-trinitro-2,4,6-trimethylaminobenzene. The role of intramolecular hydrogen bonding and steric repulsion is further investigated through comparison with four structurally related compounds differing in hydrogen-bond donor availability and substituent size.
