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

introductionContrary to common believe, some studies have reported the existence of observer dreams, in which the dreamer does not intervene. Parkinson's disease (PD) patients frequently report alterations in dream content, but nothing is known regarding this feature. Our objective was to assess the frequency of observer dreams in PD and correlation with clinical features.

methodsDreams reports were collected from a 15-day diary and classified in non-observer and observer dreams. Patients were assessed for disease related variables, including motor and non-motor dysfunction.

resultsWe collected a total of 120 dreams from 24 PD patients. Eleven had at least one observer dream. There was a total of 14 (11.7%) observer dreams, which is line with studies performed in younger patients. The relative frequency of observer dreams was negatively and significantly associated with motor function scores, bradykinesia in particular. DISCUSSION: This hints at a complex relation between dream content and neurodegeneration of motor function circuits.
