Does attention bias modification induce structural brain changes? A commentary on Abend et al. (2019).
Article in Biological psychology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 strength of research conclusions must follow from the strength of evidence. In this commentary I raise several issues with a recent paper "Brain structure changes induced by attention bias modification training" (Abend et al., 2019). I follow the paper's five highlights to discuss; the absence of discussion of negative ABM results, the low power of the study itself. Centrally, I raise the concern that the conclusions rest all their weight on a single statistically significant group x time interaction form brain-wide analysis. Most importantly, this test is not internally consistent following statcheck. The reported result requires checking, and potentially a correction that would shift the results entirely.
