Effect of eight-form Tai Chi combined with olfactory stimulation on working memory in older adults with mild cognitive impairment.
Trial report in Frontiers in public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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: Tai Chi integrates multisensory stimuli, including olfactory cues, to enhance cognitive functions such as working memory. This study evaluated the effects of eight-form Tai Chi combined with olfactory stimulation on working memory in older adults with mild cognitive impairment (MCI). Methods: This study used a 2 (time) × 3 (group) mixed design. Of 267 screened patients with MCI, 93 were deemed eligible and randomly assigned to one of three groups: Tai Chi group (TCG), Tai Chi combined with olfactory stimulation group (TCOG), or control group (CG). The TCG and TCOG participated in three weekly 60 min sessions for 26 weeks. The TCOG was exposed to four fragrances. Primary outcomes were the N-back task and the digit span test (DST). Secondary outcomes included the MoCA, MMSE, CSIT, GDS, SAS, and PSQI. Results: Post-intervention, both intervention groups outperformed the CG in 0-back accuracy (TCG: +0.118, 95% CI: 0.048-0.188, Conclusion: Tai Chi improved working memory and global cognition in older adults with MCI. Combining Tai Chi with olfactory stimulation yielded additional benefits, demonstrating superior efficacy in alleviating depressive symptoms and enhancing sleep quality.
