Evaluation of Mortality in Users of Pimavanserin Compared with Other Atypical Antipsychotics in Patients with Parkinson's Disease Psychosis: An Update.
Article in Drug safety, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionPimavanserin is the only antipsychotic medication approved in the USA to specifically treat hallucinations and delusions associated with Parkinson's disease psychosis (PDP).
objectiveTo compare mortality risk in patients with PDP after initiation of pimavanserin or comparator atypical antipsychotics in an overall PDP cohort and in a subcohort of patients residing in long-term care or skilled nursing facilities (LTC/SNFs).
methodsThis cohort study identified patients aged ≥ 65 years with PDP initiating pimavanserin or a comparator antipsychotic in US Medicare claims (2016-2021). Cox proportional hazards models were used to estimate hazard ratios (HRs) comparing all-cause mortality in the propensity score-matched treatment groups. Cumulative incidence curves, time period-specific relative risk, and risk difference estimates evaluated risk over time.
resultsIn this follow-up analysis, we identified 4384 pimavanserin initiators and 28,042 comparator initiators in the overall PDP cohort, and 921 pimavanserin initiators and 7963 comparator initiators in the LTC/SNF subcohort. After matching, the overall PDP cohort had 4381 patients in each treatment group, and the LTC/SNF subcohort had 905 patients in each group. The matched HR for mortality (pimavanserin versus comparator) was 0.76 (95% CI 0.68-0.85) in the overall PDP cohort and 0.90 (95% CI 0.74-1.10) in the LTC/SNF subcohort. In the overall PDP cohort, time period-specific relative risks and risk differences showed that pimavanserin initiators had a lower risk of mortality throughout the first 365 days of follow-up.
conclusionIn the overall PDP cohort, mortality risk was lower among pimavanserin initiators than comparator antipsychotic initiators.
