Cognitive rehabilitation for Parkinson’s disease dementia: a study protocol for a pilot randomised controlled trial.
Trial report in Trials, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 9 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
backgroundThere is growing interest in developing non-pharmacological treatments to address the cognitive deficits apparent in Parkinson's disease dementia and dementia with Lewy bodies. Cognitive rehabilitation is a goal-oriented behavioural intervention which focuses on improving everyday functioning through management of cognitive difficulties; it has been shown to be effective in Alzheimer's disease. To date, no studies have assessed its potential efficacy for addressing the impact of cognitive impairment in people with Parkinson's disease or dementia with Lewy bodies. METHODS/
designParticipants (n = 45) will be recruited from movement disorders, care for the elderly and memory clinics. Inclusion criteria include: a diagnosis of Parkinson's disease, Parkinson's disease dementia or dementia with Lewy bodies according to consensus criteria and an Addenbrooke's Cognitive Examination - III score of ≤ 82. Exclusion criteria include: a diagnosis of any other significant neurological condition; major psychiatric disorder, including depression, which is not related to the patient's Parkinson's disease and unstable medication use for their physical or cognitive symptoms. A single-blind pilot randomised controlled trial, with concurrent economic evaluation, will compare the relative efficacy of cognitive rehabilitation with that of two control conditions. Following a goal-setting interview, the participants will be randomised to one of the three study arms: cognitive rehabilitation (eight weekly sessions), relaxation therapy (eight weekly sessions) or treatment as usual. Randomisation and treatment group allocation will be carried out by a clinical trials unit using a dynamic adaptive sequential randomisation algorithm. The primary outcomes are patients' perceived goal attainment at a 2-months post-intervention assessment and a 6-months follow-up. Secondary outcomes include patients' objective cognitive performance (on tests of memory and executive function) and satisfaction with goal attainment, carers' perception of patients' goal attainment and patients' and carers' health status and psychosocial well-being, measured at the same time points. Cost-effectiveness will be examined to explore the design of a larger cost-effectiveness analysis alongside a full trial. DISCUSSION: This pilot study will evaluate the application of cognitive rehabilitation for the management of cognitive difficulties associated with Parkinson's disease dementia and dementia with Lewy bodies. The results of the study will inform the design of a fully powered randomised controlled trial.
