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.

Abstract

rationalePatients with obsessive compulsive disorder (OCD) demonstrate impaired cognition in some selected domains. Although serotoninergic dysfunction has been implicated in OCD, recent evidence suggests that dopamine may play a role as well.

objectiveThe aim of the study was to evaluate learning and working memory in OCD and to determine the effects of dopaminergic manipulations on these capacities.

methodsVisuospatial associative memory and spatial and verbal working memory were examined in 18 nondepressed patients with OCD and 18 matched healthy controls. The study further investigated whether acute administration of dopamine D2/D3 receptor agonist and antagonist would differentially modulate cognition in OCD. Each participant underwent the cognitive battery three times in a randomized double-blind, placebo-controlled crossover design.

resultsSignificant impairments in patients compared with controls were noted on the Cambridge Neuropsychological Test Automated Battery (CANTAB) paired associates learning (PAL) and a measure of sustained attention (rapid visual information processing, RVIP) that persisted across all sessions, with deficient strategy in the CANTAB spatial working memory task in the first session alone. Although the dopamine D2/D3 agonist, pramipexole, led to poorer performance on the PAL and RVIP tasks, no differential effects were noted between the two groups. No significant effects were noted for the D2/D3 antagonist, amisulpride.

conclusionsThe results are consistent with a specific associative memory deficit in OCD that remained robust despite possible practice effects and compensatory strategies and point to abnormal medial temporal lobe involvement in OCD in addition to the previously implicated frontostriatal loops, with no clear evidence of D2 receptor mediation.
