Post hoc exploratory analysis of the effect of foslevodopa/foscarbidopa continuous subcutaneous infusion on nocturia in patients with Parkinson's disease.

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.

Abstract
Introduction: Parkinson's disease (PD) non-motor symptom burden, including nocturia and sleep disturbances, worsens with disease progression. Continuous dopaminergic drug delivery with nocturnal infusion in PD demonstrated improvements in sleep and nocturia. Foslevodopa/foscarbidopa (LDp/CDp) provides 24-hour continuous drug delivery of levodopa/carbidopa (LD/CD) prodrugs via continuous subcutaneous infusion (CSCI). Methods: Least-squares mean nocturia changes (measured via Parkinson's Disease Sleep Scale-2 item 8) in patients with PD from a randomized 12-week phase 3 trial of LDp/CDp CSCI versus oral LD/CD (NCT04380142) and a 52-week open-label LDp/CDp CSCI phase 3 trial (NCT03781167) were analyzed post hoc via mixed-effects regression and analysis of covariance. Correlation coefficients at baseline (BL) and in change from BL to week 12 or week 52 (Δ BL-wk 12 or Δ BL-wk 52) for nocturia and quality of life (QoL, measured as Parkinson's Disease Questionnaire [PDQ-39] Summary Index score) were calculated via Spearman's test. Results: This exploratory analysis demonstrated significant and sustained improvement in nocturia symptoms from BL with LDp/CDp treatment in both the randomized (to week 12; n = 44; nominal p ≤ 0.01) and open-label (to weeks 6, 13, 26, and 52; with n = 176, 149, 107, and 75, respectively; nominal p ≤ 0.001 for all) trials. Nocturia improvement was significantly greater in LDp/CDp- versus oral-treated patients (n = 59; nominal p ≤ 0.05). A significant positive correlation between nocturia and QoL was shown at BL and between Δ BL-wk 12 in the randomized trial (nominal p ≤ 0.05 for both), while open-label results showed no significant correlations. Conclusions: LDp/CDp-treated patients with PD demonstrated significantly improved nocturia with 24-hour therapy, 12-week nocturia improvements were significantly greater than oral therapy, and patient-reported nocturia may correlate with QoL.
