Visit-to-visit systolic blood pressure variability, blood pressure treatment intensity, and cognitive decline.

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
introductionVisit-to-visit blood pressure variability (BPV) may be associated with cognitive decline beyond mean blood pressure (BP), but its relevance across treatment contexts remains uncertain.
methodsWe pooled individual-participant data from Action to Control Cardiovascular Risk in Diabetes Memory in Diabetes (ACCORD-MIND) and Systolic Blood Pressure Intervention Trial Memory and Cognition in Decreased Hypertension (SPRINT-MIND) (n = 11,104). Participants had baseline and follow-up cognitive testing and ≥3 BP measurements from 3 months onwards. The primary exposure was systolic BP variation independent of the mean (SBP-VIM). The primary outcome was annualized change in standardized Digit Symbol Substitution or Coding Test Z-scores.
resultsEach 10% increment in SBP-VIM was independently associated with faster annual cognitive decline (β = -0.008 per year; 95% confidence interval [CI]: -0.014 to -0.003) after adjustment including mean SBP. Associations were observed in the intensive but not standard BP treatment arms of both trials, although the pooled interaction was not statistically significant (p = 0.054). DISCUSSION: Higher systolic BPV was associated with accelerated cognitive decline independently of mean BP. The exploratory treatment-context pattern warrants prospective confirmation.
