Ropinirole prolonged release: in advanced Parkinson's disease.
Review in CNS drugs, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Ropinirole prolonged release is a non-ergoline dopamine receptor agonist that is indicated for the treatment of Parkinson's disease. * Once-daily ropinirole prolonged release and three-times-daily ropinirole immediate release have similar exposure over 24 hours. The prolonged-release formulation is associated with fewer fluctuations in plasma ropinirole concentrations. * Two well designed, placebo- or active comparator-controlled trials examined the efficacy of ropinirole prolonged release in patients with advanced Parkinson's disease suboptimally controlled by levodopa. In the placebo-controlled trial, 24 weeks' therapy with ropinirole prolonged release 6-24 mg once daily reduced hours of 'off' time (primary endpoint) to a significantly greater extent than placebo. In the active comparator-controlled trial, significantly more ropinirole prolonged-release recipients than ropinirole immediate-release recipients maintained a >or=20% reduction from baseline in 'off' time at week 24 (primary endpoint). *Ropinirole prolonged release 6-24 mg once daily was generally well tolerated in patients with advanced Parkinson's disease; adverse events were generally typical of non-ergoline dopamine receptor agonists.
