Efficacy of 5-Hz Transcranial Magnetic Stimulation Over the Left Dorsolateral Prefrontal Cortex in Improving Cognitive Function During the Recovery Phase of Stroke.
Article in Brain and behavior, 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
objectiveHere, we aimed to explore the efficacy of 5-Hz transcranial magnetic stimulation (TMS) over the left dorsolateral prefrontal cortex (DLPFC) in improving cognitive function during the recovery phase of stroke.
methodThis was a retrospective study. A total of 33 patients were enrolled, of whom 13 received 5-Hz TMS treatment and 20 did not. Cognitive functioning was assessed before and after treatment.
resultsMontreal Cognitive Assessment (MoCA) scores increased significantly after treatment in the TMS group compared with the control group (p = 0.0359). MoCA scores in the TMS group also increased significantly after treatment compared with before (p < 0.0001). In the TMS group (including the left-side lesions subgroup and the right-side lesions subgroup), MoCA scores increased only in patients who had received left-side lesions (p = 0.0156). However, we did not find any significant between-group differences in MoCA scores after treatment.
conclusionHigh-frequency (5 Hz) TMS applied to the left DLPFC significantly enhances overall cognitive functioning in patients who are recovering from strokes. Interestingly, we found that when 5-Hz TMS was applied to the left DLPFC, its effects were similar regardless of whether the lesion was ipsilateral to the stimulation site or not.
