Article in Journal of chemical ecology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Xenos peckii is a strepsipteran parasitoid of the common North American paper wasp, Polistes fuscatus. Mate-seeking X. peckii males respond to a long-range sex pheromone emitted by the female, which remains permanently embedded within the abdomen of a mobile host wasp. During peak pheromone signalling, we excised the female from her host, severed the cephalothorax containing the pheromone gland, extracted it in hexane, and analyzed aliquots of combined extracts by coupled gas chromatographic-electroantennographic detection (GC-EAD). These analyses revealed a candidate pheromone component (CPC) that consistently elicited strong responses from male antennae. We identified the CPC as (7E,11E)-3,5,9,11-tetramethyltridecadienal based on its retention indices (RI) on three GC-columns, RI inter-column differentials, mass and NMR spectra, and synthesis of an authentic standard that matched the GC-retention and spectrometric characteristics of the CPC. For a field experiment, we prepared (7E,11E)-3,5,9R,11-tetramethyltridecadienal and (7E,11E)-3,5,9S,11-tetramethyltridecadienal. Xenos peckii males were caught in traps baited with either compound singly or a 1:1 mixture of the two but not in unbaited control traps. The sex pheromone of X. peckii resembles that reported for the strepsipterans Stylops mellittae and S. muelleri, (R,R,R)-3,5,9-trimethyldodecanal, suggesting a common biosynthetic pathway across taxonomic genera.
