Sleep and Quality of Life Under Prolonged Release Oxycodone/Naloxone for Severe Restless Legs Syndrome: An Analysis of Secondary Efficacy Variables of a Double-Blind, Randomized, Placebo-Controlled Study with an Open-Label Extension.
Trial report in CNS drugs, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01112644 (A Randomised, Double-blind, Placebo-controlled, Parallel-group, Multicenter Study to Demonstrate Improvement of Symptoms of RLS in Subjects With Moderate to Severe Idiopathic RLS With Daytime Symptoms Who Take OXN PR Compared to Subjects Taking Placebo), which is not on this map.

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.

Abstract
objectiveThe aim was to assess the effects of prolonged release oxycodone/naloxone (OXN PR) on sleep and quality of life (QoL) in patients with severe restless legs syndrome (RLS) refractory to first-line dopaminergic RLS treatment.
methodsSleep and QoL data from a 12-week, randomized, double-blind, placebo-controlled study with subsequent 40-week, open-label extension were analyzed. Instruments included the Medical Outcomes Study (MOS) sleep scale, RLS-6 rating scale, and RLS-QoL questionnaire.
resultsThe full analysis population included 132 OXN PR and 144 placebo patients. After 12 treatment weeks, improvements in the MOS domains 'sleep disturbance' [-18.6; 95 % confidence interval (CI) -24.4 to -12.9; p < 0.0001], 'sleep adequacy' (14.9; 95 % CI 7.9-21.9; p < 0.0001), and 'sleep quantity' (0.77 h; 95 % CI 0.43-1.11; p < 0.0001) were significantly greater under OXN PR than under placebo. OXN PR also reduced symptom severity (when falling asleep and during the night) and daytime tiredness, and increased sleep satisfaction to a significantly greater extent than placebo (all p < 0.001; RLS-6). QoL improved in both treatment arms, with a significant difference of -9.02 (95 % CI -12.85 to -5.19; p < 0.001) in the mean sum score in favor of OXN PR. All sleep and QoL aspects also improved under 40 weeks of open-label OXN PR treatment.
conclusionsOXN PR improved RLS symptom severity and sleep quantity and adequacy, resulting in greater sleep satisfaction, less daytime tiredness, and improved QoL. In appropriate patients, OXN PR should be considered as an alternative treatment option for severe RLS that cannot be controlled by first-line dopaminergic medications.
