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
backgroundConflicting evidence exists regarding the associations between headache- and cognition, with conventional methods failing to capture the heterogeneous cognitive trajectories. We investigated dynamic relationships using group-based trajectory modeling (GBTM).
methodsThis longitudinal analysis included 2,949 participants aged ≥45 from the China Health and Retirement Longitudinal Study (CHARLS, 2011-2020). Headache was ascertained via a standardized questionnaire. Cognitive trajectories were derived from global cognition Z-scores using GBTM. Multinomial logistic regression evaluated headache-cognition associations, adjusting for demographics, health behaviors, and comorbidities. Stratified analyses tested effect modification by demographics, health behaviors, and comorbidities
resultsGBTM identified three cognitive trajectories: low (17.5%), medium (43.8%), and high (38.7%). Headache significantly increased the probability of belonging to low (OR = 1.29, 95% CI: 1.11–1.50; p < 0.001) and medium trajectories (OR = 1.14, 95% CI: 1.01–1.30; p = 0.033). Alcohol, hypertension, and stroke amplified associations, while diabetes paradoxically attenuated them (p for interaction < 0.05).
conclusionHeadache independently predicts adverse cognitive trajectories, with alcohol, hypertension, and stroke acting as critical effect modifiers. Paradoxically, diabetes attenuated this risk. Integrating headache screening into cognitive risk stratification and targeting modifiable factors may mitigate cognitive risk.
