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
Egg parasitoids have evolved various strategies to overcome the reliability-detectability problem and efficiently parasitize host eggs. Identifying what cues egg parasitoids use is important to increase their efficiency as biocontrol agents. In this study, we investigated the role of chemical cues from eggs and defensive compounds of the pistachio green stink bug (PGSB), Acrosternum arabicum (Hemiptera: Pentatomidae), on the foraging behavior and adult sex discrimination by the egg parasitoid Psix saccharicola (Hymenoptera: Scelionidae). Parasitoid responses to volatiles from PGSB egg masses and sex-specific metathoracic gland (MTG) extracts were evaluated using a Y-tube olfactometer. We found that P. saccharicola was significantly attracted to volatiles emitted by egg masses and to MTG extracts from both sexes. However, parasitoids did discriminate between males and females by displaying longer residence times in the arm containing the female MTG extract. Gas chromatography analysis showed that MTG and egg masses extracts contained largely similar chemical profiles, consisting of various alkanes, aldehydes and esters, with the major compounds being tridecane, (E)-2-decenal, and (E)-2-decenyl acetate. Our SEM analysis suggest that MTG secretions are passively deposited onto the eggs. Together, our findings suggest that PGSB volatile compounds from the MTG attract the egg parasitoid, which may be useful in developing semiochemical-based biological control strategies against PGSB.
