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

backgroundAs Parkinson's disease (PD) progresses, patients and their families experience substantial health and economic burdens. Because motor fluctuations (also called 'off-time') are linked to poor quality of life and higher healthcare costs, minimizing off-time is an effective strategy for reducing costs associated with PD.

objectiveTo assess the cost utility of rasagiline or entacapone as adjunctive therapies to levodopa versus levodopa/carbidopa/entacapone (LCE) versus standard levodopa monotherapy in patients with advanced PD and motor fluctuations in the US.

methodsA 2-year stochastic Markov model was utilized to examine the cost effectiveness of treatments of advanced PD. The model assumed that patients transition health status every 4 months. Transition probabilities, including uncertainties, were estimated from clinical trial data. Medical costs, daily drug costs and utility weights were obtained from published literature.

resultsOver 2 years, all therapy options showed greater effectiveness than levodopa alone. Rasagiline+levodopa and LCE were cost saving from a payor perspective, while entacapone+levodopa was cost saving from a societal perspective. Mean benefits over 2 years were 0.12 (90% credibility interval [CI] 0.07, 0.18) additional quality-adjusted life-years (QALYs) for rasagiline+levodopa, entacapone+levodopa and LCE, 5.08 (90% CI 3.87, 6.28) additional months with <or=25% off-time for rasagiline+levodopa and 4.85 (90% CI 3.63, 6.06) additional months with <or=25% off-time for entacapone+levodopa and LCE versus levodopa alone.

conclusionFrom a payor perspective, rasagiline+levodopa and LCE were dominant therapies over levodopa monotherapy, while entacapone+levodopa was effective at a higher cost. With no additional cost over a 2-year period, rasagiline+levodopa presents a valuable alternative to entacapone+levodopa, LCE and levodopa monotherapy in the treatment of advanced PD patients. Results from this cost-utility model and prior adjunctive clinical data provide ongoing support for the adjunctive use of rasagiline in advanced PD patients with motor fluctuations.
