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

The synthesis of racemic isochromans from cashew nut shell liquid (CNSL) derived anacardic acids is described. Two key steps for the synthesis of the isochromans were utilized. (i) The benzylic bromination of methyl 2-methoxy-6-pentadecylbenzoate was accomplished with N-bromosuccinimide in the green solvent tert-butyl acetate to afford methyl 2-methoxy-6-(pentadec-1-en-1-yl)benzoate. (ii) Exposure of the secondary alcohol 1-(2-methoxy-6-(pentadec-1-en-1-yl)phenyl)ethanol to potassium tert-butoxide resulted in the formation of the isochroman, trans-8-methoxy-1-methyl-2-tridecylisochroman. In a similar manner, the related isochroman, trans-8-methoxy-1,3-dimethylisochroman, could be synthesized. Selected antifungal and antibacterial testing showed moderate activities.
