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

One of the most common types of modification of secondary metabolites is the acylation of oxygen- and nitrogen-containing substrates to produce esters and amides, respectively. Among the known acyltransferases, the members of the plant BAHD family are capable of acylating a wide variety of substrates. Two full-length acyltransferase cDNAs (LaAT1 and 2) were isolated from lavender flowers (Lavandula angustifolia L.) by reverse transcriptase-PCR using degenerate primers based on BAHD sequences. Recombinant LaAT1 exhibited a broad substrate tolerance accepting (hydroxy)cinnamoyl-CoAs as acyl donors and not only tyramine, tryptamine, phenylethylamine and anthranilic acid but also shikimic acid and 4-hydroxyphenyllactic acid as acceptors. Thus, LaLT1 forms esters and amides like its phylogenetic neighbors. In planta LaAT1 might be involved in the biosynthesis of rosmarinic acid, the ester of caffeic acid and 3,4-dihydroxyphenyllactic acid, a major constituent of lavender flowers. LaAT2 is one of three members of clade VI with unknown function.
