Refinements of the phase adjustment task (PAT 2.0).
Article in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
In 2021 a new measure for the assessment of cardiac interoceptive accuracy-the Phase Adjustment Task (PAT)-was developed that overcomes several limitations of existing methods and can be administered using a smartphone application. In this report, we describe several refinements to the PAT. These include: (1) triggering tones from the detection of the heartbeat via the smartphone camera, rather than using an algorithm for predicting the occurrence of the next heartbeat; (2) technical amendments to enable implementation on iPhones with multiple cameras; (3) changes to instructions and (4) changes to the collection of confidence ratings to improve participant understanding and the utility of confidence ratings for interpretation of results; (5) the introduction of new practice trials to improve clarity; (6) changes to the analysis approach to identify cardiac phase-based heartbeat perceivers; (7) a review of the use of continuous scores; (8) a reanalysis of data comparing PAT performance in supervised laboratory settings and unsupervised remote settings using the new analysis method, and (9) the implementation of additional measures to discourage participants from checking their pulse. In this paper we outline our justification for these changes and provide details of where researchers can access the materials required for implementing the PAT and analyzing data. Finally, we provide further recommendations for implementation.
