1 · What the graph read from 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.

2 · The registry

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

Studies comparing the effects of Angiotensin II (Ang-II) stimulating and inhibiting antihypertensive medications (AHMs) on dementia risk have reported inconsistent findings. Based on the PRISMA guidelines, this study was performed to pool these findings. We searched PubMed, Scopus, Embase Ovid, PsycINFO, and CINAHL from inception to 22 May 2024 for randomised controlled trials (RCTs) and observational studies that compared the use of Ang-II stimulating (thiazides, Ang-II receptor blockers, and dihydropyridine calcium channel blockers) and inhibiting AHMs (β-blockers, angiotensin-converting enzyme inhibitors, and non-dihydropyridine calcium channel blockers) and the subsequent risk of developing dementia. Two reviewers independently performed study selection, data extraction, and quality assessment. Random effects meta-analysis models were used to calculate hazard ratios (HRs) or risk ratios (RRs) with their confidence intervals (CIs). All-cause dementia was the primary outcome. Alzheimer's disease (AD), vascular dementia (VD), and mild cognitive impairment (MCI) were secondary outcomes. We included 18 studies with 1,883,283 participants. Observational studies showed that the use of Ang-II stimulating AHMs reduced the risk of all-cause dementia by 13% (HR = 0.87; 95% CI = 0.82-0.93) compared with Ang-II inhibiting AHMs. The risk of AD was reduced by 12% (HR = 0.88; 95% CI = 0.86-0.90), VD by 19% (HR = 0.81; 95% CI = 0.72-0.91), and MCI by 24% (HR = 0.76; 95% CI = 0.68-0.85) in these studies. A meta-analysis of four RCTs revealed a non-significant 8% reduction in dementia risk with Ang-II stimulating AHMs versus control (RR = 0.92; 95% CI = 0.79-1.08). Observational evidence suggests that Ang-II stimulating AHMs may offer neuroprotective benefits relative to Ang-II inhibiting AHMs.
