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: There is a lack of research on the trajectories of cognitive functioning in older people with hypertension, as well as possible contributing factors and correlations between cognitive functioning and mental health. Objective: This study aimed to conduct a secondary longitudinal analysis to examine cognitive functioning trajectories and their associated factors in older people with hypertension. Methods: The data used in our study were retrieved from the Chinese Longitudinal Healthy Longevity Survey. The Chinese version of the Mini-Mental State Examination was used to assess cognitive functioning. The trajectories of cognitive functioning of older individuals with hypertension were determined by using group-based trajectory modeling. The binary logistic regression analyses were performed to examine how participant factors affected the trajectories of cognitive functioning in older individuals with hypertension. The relationships between cognitive functioning and mental health were investigated using multivariable linear regression models. Data were analyzed using SPSS (version 20.0; SPSS Inc) and Stata (version 16.0; StataCorp LLC). Results: A total of 642 older people with hypertension were included. Cognitive functioning was categorized into 2 trajectories according to group-based trajectory modeling: "rapid decline" (48/642, 7.9%) and "slow decline" (594/642, 92.1%). Binary logistic regression results showed that older adults with hypertension aged equal to or greater than 80 years had an elevated risk of rapid decline in cognitive functioning (odds ratio 5.484, 95% CI 2.365-12.719), and higher score in mental health was the protector of rapid decline in cognitive functioning during the following 13 years (odds ratio 0.918, 95% CI 0.852-0.988). In the unadjusted model, mental health was positively associated with cognitive functioning (β=.246, 95% CI 0.125-0.234, P<.001), and this association was maintained after partial or complete adjustment for covariates (β=.159, 95% CI 0.059-0.174, P<.001; β=.138, 95% CI 0.043-0.158, P=.001). Subgroup analyses by age showed that this positive correlation was only seen in the 60-69 years age group (β=.183, 95% CI 0.036-0.193, P=.004), while subgroup analyses by sex revealed that the association between these 2 indicators was no longer presented among males in the fully adjusted model (β=.082, 95% CI -0.024 to 0.119, P=.19), and BMI fully stratification demonstrated this association persisted in the healthy weight group (β=.125, 95% CI 0.039-0.210, P=.004). Conclusions: Our research showed that the decline in cognitive functioning is associated with lower mental health and occurs more rapidly in older adults with hypertension who are older than 80 years.
