Association of diabetes with dyskinesia in older psychosis patients.
Trial report in Psychopharmacology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
rationaleOlder patients treated with antipsychotics are more likely to develop tardive dyskinesia (TD) than younger individuals. Advanced age is also an important risk factor for diabetes, which may be associated with TD. These observations suggest that older diabetic patients may be particularly vulnerable to developing TD.
objectiveTo examine whether older psychosis patients with diabetes exhibit more severe dyskinesia than well-matched patients without diabetes and to test whether there are differences in dyskinesia severity between diabetic patients treated with conventional versus atypical antipsychotics versus those not taking antipsychotic medications.
methodSixty-one psychosis patients with diabetes and 122 case-matched non-diabetic comparison patients were studied. Observer-based and quantitative instrumental measures were administered to assess prevalence and severity of dyskinesia. Raters were unaware of patients' diabetes status.
resultsDiabetic patients exhibited significantly more severe TD than non-diabetic comparison patients. Groups did not differ in terms of severity of parkinsonism. Significantly more diabetic (27.9%) than non-diabetic (14.6%) patients met research diagnostic criteria for TD. Diabetic patients treated with atypical antipsychotics at the time of assessment had significantly more severe TD than all other patient subgroups, including patients treated with conventional antipsychotics. Results from the instrumental measures of force steadiness were consistent with observer-based severity ratings.
conclusionThe deleterious effect of diabetes on TD in the absence of any effect of parkinsonism supports preclinical studies of glucose-related dopamine hyperfunction and has implications for the pharmacologic management of psychosis in patients with pre-existing diabetes.
