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

Doty (Odors as cognitive constructs: history of odor classification and attempts to map odor percepts to physical and chemical parameters. 2025. Chem Senses 50:bjaf022) provides a thorough historical review of odor classification but underestimates recent advances in quantifying odor space. He argues that odor qualities are cognitive constructs that do not map well to physicochemical properties. While odor is indeed cognitively mediated, practical and predictive rules for olfaction exist and continue to improve. Therefore, we suggest that Doty's historical review should be read not as a eulogy for physicochemical modeling, but as a historical baseline that the field is now surpassing.
