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

purposeAlpha-blockers and 5-alpha reductase inhibitors (5ARIs) are well-established treatments for symptoms of benign prostatic hyperplasia (BPH). Despite their therapeutic benefits, concerns have been raised regarding a potential association between these medications and an increased risk of dementia. However, current evidence remains inconsistent, highlighting the need for further evaluation. This study aims to assess the potential dementia risk among patients receiving alpha-blockers and 5ARIs.

methodsFollowing PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines (PROSPERO CRD42025643431), 7 databases were systematically searched through December 2024 for studies examining the association between alpha-blockers or 5ARIs and dementia risk in patients with BPH. Risk of bias was assessed using the ROBINS-I (Risk of Bias in Non-randomized Studies of Interventions) tool. A Bayesian network meta-analysis was performed to estimate risk ratios with 95% credible intervals and to generate surface under the cumulative ranking curve (SUCRA) values.

resultsFive multicenter studies involving 3,650,434 patients (mean age, 71.1 years) and demonstrating an overall low risk of bias were included. The network analysis indicated that neither alpha-blockers nor 5ARIs were significantly associated with an increased risk of dementia compared with no treatment. However, SUCRA values suggested a relatively higher probability of dementia risk for 5ARIs (finasteride and dutasteride), followed by tamsulosin, doxazosin, terazosin, and alfuzosin.

conclusionThis study found no significant association between the use of alpha-blockers or 5ARIs and increased dementia risk. These findings may assist clinicians in making more informed prescribing decisions, particularly for older male patients with BPH. Further large-scale research with extended follow-up periods is needed to strengthen the evidence across all BPH medications.
