The Mediating Role of Depression in the Relationship Between Perceived Injustice and Pain Intensity Among Fibromyalgia Patients.
Article in Journal of pain research, 2025. 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
Background: Fibromyalgia (FM) patients often perceive heightened levels of injustice, which can be associated with depressive symptoms. Despite this connection, the mediating role of depression between perceived injustice and pain intensity in FM patients remains unexplored. Aim: This study explored whether depression mediates the relationship between perceived injustice and pain intensity in FM. Methods: Data were collected through an online survey distributed to FM patients at the Tel Aviv Sourasky Medical Center, Israel. A total of 161 FM patients completed the survey, with perceived injustice assessed using the Injustice Experience Questionnaire, depression evaluated using the Patient Health Questionnaire, and pain intensity measured with the numerical Pain Intensity Rating Scale. Statistical analyses included analysis of variance and bootstrap-based mediation models. Results: FM patients reported elevated levels of pain, perceived injustice, and depression. The study found that depression significantly mediated the association between perceived injustice and pain intensity in FM patients (P < 0.001, CI = 0.024, 0.312). Conclusion: The link between perceived injustice and pain intensity in FM is partially explained by the level of depression. Individuals with higher perceived injustice scores are more susceptible to depression, subsequently experiencing increased pain. These findings suggest that intervention programs targeting depression may mitigate the impact of perceived injustice on pain intensity in FM, potentially enhancing health-related quality of life.
