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

Fluorescent analogues of the gypsy moth sex pheromone (+)-disparlure (1) and its enantiomer (-)-disparlure (ent-1) were designed, synthesized, and characterized. The fluorescently labelled analogues 6-FAM (+)-disparlure and 1a 6-FAM (-)-disparlure ent-1a were prepared by copper-catalyzed azide-alkyne cycloaddition of disparlure alkyne and 6-FAM azide. These fluorescent disparlure analogues 1a and ent-1a were used to measure disparlure binding to two pheromone-binding proteins from the gypsy moth, LdisPBP1 and LdisPBP2. The fluorescence binding assay showed that LdisPBP1 has a stronger affinity for 6-FAM (-)-disparlure ent-1a, whereas LdisPBP2 has a stronger affinity for 6-FAM (+)-disparlure 1a, consistent with findings from previous studies with disparlure enantiomers. The 6-FAM disparlure enantiomers appeared to be much stronger ligands for LdisPBPs, with binding constants (K
