The impact of anticholinergics on cognitive function in patients with neurogenic lower urinary tract dysfunction: A narrative review.
Review in Indian journal of urology : IJU : journal of the Urological Society of India. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
This narrative review discusses the relationship between anticholinergic medications and cognitive change specifically in patients with neurogenic lower urinary tract dysfunction (NLUTD). NLUTD is prevalent in various conditions, including spinal cord injury (SCI), spina bifida (SB), multiple sclerosis (MS), Parkinson's, stroke, and dementia and often requires anticholinergic overactive bladder (OAB) medications. In the general population, and among those with OAB, several studies have found a significant association between this class of medications and cognitive side effects, mostly when used for > 90 days. These cognitive side effects may be particularly relevant to people with NLUTD due to their higher baseline risk of cognitive impairment. Two studies (one in people with SCI and another in MS) found evidence of cognitive impairment with the use of OAB anticholinergics (specifically oxybutynin and tolterodine). People with dementia commonly use OAB anticholinergics, and there is evidence that oxybutynin and tolterodine may impair cognition in this population. Two recent studies in children with SB studied 12 months of solifenacin and 6 months of fesoterodine/oxybutynin and found there was no significant change in neuropsychological testing. Clinical studies in people with Parkinson's disease and prior stroke have not shown that trospium, darifenacin, or fesoterodine have a significant impact on cognitive measures. In summary, oxybutynin and tolterodine may pose a higher risk of cognitive impairment than newer OAB anticholinergics in people with NLUTD; there is no evidence that children with SB experience cognitive impairment with OAB anticholinergics. Further study is necessary to confirm cognitive safety, particularly as the NLUTD population may have a high exposure to OAB anticholinergics. Advocating for potentially safer OAB medications is necessary if there is concern about cognitive risks.
