Association between peripheral platelet markers and motoric cognitive risk syndrome: a cross-sectional analysis of data from the WCHAT study.
Article in BMJ open, 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
objectivesTo investigate the association between peripheral platelet indices and motoric cognitive risk syndrome (MCR).
designA cross-sectional analysis using baseline data from the West China Health and Aging Trend (WCHAT) study.
settingCommunity settings across several ethnically diverse regions of western China.
participantsFrom an initial pool of 7536 community-dwelling adults in the WCHAT study, 4080 participants were included in the final analysis after applying exclusion criteria. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was MCR, defined by the concurrent presence of subjective cognitive complaints and slow gait speed (≥1 SD below sex- and age-stratified mean) in the absence of dementia or mobility disability. The exposures were platelet indices, including platelet count (PLT), mean platelet volume, platelet distribution width (PDW), platelet-large cell ratio (P-LCR) and platelet crit (PCT). Multivariable logistic regression was used to examine the associations between platelet indices and MCR. Restricted cubic spline analysis was performed to explore non-linear associations.
resultsAmong the 4080 participants, 320 (7.84%) met the diagnostic criteria for MCR. After adjustment for potential confounders, higher PLT (OR=1.17, 95% CI 1.04 to 1.32, p=0.007) and PCT (OR=1.13, 95% CI 1.01 to 1.26, p=0.046) were associated with greater odds of MCR. Conversely, higher PDW (OR=0.85, 95% CI 0.75 to 0.97, p=0.014) and P-LCR (OR=0.87, 95% CI 0.77 to 0.98, p=0.026) were associated with lower odds of MCR. Furthermore, a nonlinear relationship was identified for PDW and MCR (p<0.05), with a threshold at 13.40%.
conclusionsSpecific platelet indices are significantly associated with MCR. Further prospective studies are warranted to confirm these associations and explore the underlying mechanisms. TRIAL REGISTRATION NUMBER: China Clinical Trial Center (ChiCTR1800018895).
