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

Two concise and efficient synthetic routes were developed for the synthesis of three 1,7-diarylheptanoids (1-3) containing a 1,4-pentadiene unit, which were originally isolated from Ottelia acuminata var. acuminata. The first approach focused on the construction of linear diarylheptanoids 1 and 3 featuring a (1E,4E)-pentadiene moiety, via a Suzuki coupling reaction. The second strategy enabled the synthesis of sixteen-membered macrocyclic ether 2 with a (1Z,4E)-pentadiene unit. The challenging macrocyclization was successfully accomplished through an Ullmann coupling. Notably, the formation of the Z-olefin within the macrocyclic framework was promoted by the inherent ring strain of diarylether-type heptane system, which preferentially stabilizes this particular configuration.
