Quantifying observational evidence for risk of dementia following androgen deprivation therapy for prostate cancer: an updated systematic review and meta-analysis.
Synthesis in Prostate cancer and prostatic diseases, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
backgroundAndrogen deprivation therapy (ADT) administration was recently reported and might be positively associated with dementia. However, the existing studies showed controversial results. The aim of this study was to evaluate the relationship between ADT and the risk of dementia through a meta-analysis.
methodsOriginal articles published up to March 2020 were retrieved from Embase, Pubmed, the Cochrane library, and Web of Science for studies focusing on associations between ADT for prostate cancer (PCa) and incidence of dementia. A meta-analysis was conducted using a hazard ratio (HR) and 95% confidence interval (CI) as effect measures. Heterogeneity between the studies was examined using I
resultsThirteen studies were included in this systematic review. Eleven cohort studies involving 339,400 cases and 436,851 controls were included in the main meta-analysis. ADT administration was associated with a 21% increase in dementia risk (pooled HR = 1.21, 95% CI: 1.13-1.30, P < 0.001). Subgroup analyses based on ADT types showed that luteinizing hormone-releasing hormone agonists (HR = 1.14, P < 0.001), bilateral orchiectomy (HR = 1.42, P < 0.001), oral antiandrogens (HR = 1.35, P = 0.138), and combined androgen blockade (HR = 1.22, P = 0.097) were positively related to subsequent risk of dementia, although the differences were not statistically significant with oral antiandrogens and combined androgen blockade.
conclusionsThe current study indicated that ADT administration, no matter with types of ADT, is associated with the risk of dementia in patients with PCa. Future studies are needed to determine whether ADT causes dementia or is merely associated with increased risk.
