The effects of transcranial magnetic stimulation on state and trait anxiety among undergraduates with insomnia symptoms: a randomized control trial.
Trial report in BMC psychology, 2026. 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
backgroundsTo investigate the effects of rTMS on state and trait anxiety among undergraduates with insomnia symptoms.
methodsForty-one participants were randomized to the active rTMS group (n = 21) or sham group (n = 20). 32 participants completed all assessments and were included in the final analysis (Active group: 17; Sham group: 15). Participants received 1 Hz rTMS interventions targeting the left dorsolateral prefrontal cortex for 2 weeks, comprising 10 sessions (active vs. sham stimulation). Sleep quality and anxiety were assessed using the Pittsburgh Sleep Quality Index (PSQI) and the State Trait Anxiety Inventory (STAI) at baseline(T0), post-intervention(T1), and 8 weeks' follow-up(T2).
resultsMixed ANOVA results showed that, following the intervention, compared to the Sham group, the Active Group showed significant improvements in PSQI and STAI-S scores, and the Group×Time interaction effect was significant (PSQI: F (2, 60) = 5.27, P = 0.008; STAI-S: F (2, 60) = 9.09, P < 0.001). Simple effects showed that at both T1 and T2, the PSQI of the Active group was lower than that of the Sham group (P < 0.01); at T2, the STAI-S of the Active group was lower than that of the Sham group (P < 0.05).
conclusionsCompared with sham stimulation, 1 Hz rTMS can effectively improve insomnia and state anxiety among undergraduates, and the improvement effect persists at the 8-week follow-up.
