Prospective associations between major depressive disorder, generalized anxiety disorder, fibromyalgia, and myalgic encephalomyelitis/chronic fatigue syndrome.
Article in Psychological medicine, 2025. 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
backgroundFunctional disorders (FDs) are associated with internalizing disorders (IDs). Studies investigating the nature of these associations over time are limited. We tested the direction of causation between measures of IDs (major depressive disorder [MDD], generalized anxiety disorder [GAD]) and FDs (fibromyalgia [FM] and myalgic encephalomyelitis/chronic fatigue syndrome [ME/CFS]) measured across two waves of longitudinal data (
methodsThe Lifelines Cohort Study is a large prospective population-based cohort study in the northeast of the Netherlands. We tested competing causal models for the longitudinal association between IDs and FDs and, to follow-up results from the model with all IDs and FDs, tested the direction of causation between MDD and FM.
resultsFDs were more stable over time than IDs. Initial model comparisons support a bidirectional relationship between most IDs and FDs. Follow-up analyses support a unidirectional model where FM predicts MDD over time (
conclusionsThe cross-time associations between ME/CFS, MDD, and GAD appear bidirectional (causal in both directions). Our results are consistent with, but not demonstrative of, a causal relationship from FM to MDD. The consequences of specific FDs vary, underscoring the value of studying these conditions as distinct constructs.
