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

Real Christmas trees contribute ~$2.5 billion to the US economy annually. True fir (Abies spp.) are the most popular trees and account for the majority of sales. The real Christmas tree commodity board identified aroma as the primary driver for consumers to purchase a real tree. We conducted consumer aroma panels for five (Fraser, noble, Nordmann, Trojan, and concolor) of the most popular fir Christmas trees in the US. Based on aroma characteristics alone, Fraser fir was found to be most liked while noble fir ranked last amongst consumers. Gas Chromatography Mass Spectroscopy metabolite profiling of terpene (the major drivers of conifer aroma) putatively identified 132 mono- and sesquiterpene and 48 diterpene metabolites across all five species. Among these, the sesquiterpene, β-bisabolene, was strongly correlated with consumer liking. These findings provide a resource to identify compounds positively associated with consumer preference to help guide Christmas tree genetic improvement efforts.
