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

Hexaazatrinaphthylene (HATNA) has recently been a subject of great interest as a polycyclic heteroaromatic scaffold in materials science, specifically in the field of discotic liquid crystals (DLCs), battery cathodes, n-type semiconductors, and so on. However, little is known about the photophysical properties of HATNA derivatives. Here we report the synthesis of a new class of hexa(arylethynyl) HATNA derivatives via consecutive Sonogashira coupling. This protocol showed good functional-group tolerance and moderate to good yields were achieved. The obtained HATNA products showed favorable photophysical properties, with molar absorption coefficients up to 1.69 × 10
