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
The detection of the geomagnetic field by animals to use as a cue in homing and migration is known as magnetoreception. The ferromagnetic hypothesis explains magnetoreception assuming that magnetic nanoparticles in cellular structures are used as magnetic field transducers. Considering magnetoreception in social insects, the most studied has been the honeybee Apis mellifera and only in two wasp species (Vespa orientalis and Polybia paulista) have been shown a magnetosensitive behavior. In the present report the body parts (abdomen, head and antennae) of Polistes versicolor and Polybia paulista wasps were studied aiming to find biomineralized magnetic nanoparticles, using magnetometry measurements and ferromagnetic resonance spectroscopy. The magnetometry measurements show the presence of magnetic nanoparticles in all body parts, being characterized as mixtures of superparamagnetic, single domain and pseudo-single domain nanoparticles. From the ferromagnetic resonance spectra were obtained the asymmetry ratio A and the effective g factor g
