Peripheral PDLIM5 expression in bipolar disorder and the effect of olanzapine administration.
Article in BMC medical genetics, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundOne of the genes suggested to play an important role in the pathophysiology of bipolar disorder (BPD) is PDLIM5, which encodes LIM domain protein. Our main objective was to examine the effect of olanzapine treatment on PDLIM5 mRNA expression in the peripheral blood leukocytes of BPD patients.
methodsWe measured the expression of PDLIM5 mRNA from 16 patients with BPD Type I after 0, 4, and 8 weeks of treatment with olanzapine using quantitative real-time PCR. The Young Mania Rating Scale was used to evaluate the severity of manic symptoms in BPD patients. We also compared PDLIM5 mRNA expression in treatment-naïve BPD patients with that in healthy control subjects.
resultsNo significant difference was found in PDLIM5 mRNA expression between patients before olanzapine treatment and following 4 and 8 weeks of treatment (p>0.05). Although we observed a significant reduction in the severity of manic symptoms in all BPD patients (p<0.05), the effectiveness of the medication did not significantly correlate with the expression of PDLIM5 mRNA (p>0.05). Interestingly, PDLIM5 mRNA expression differed significantly between treatment-naïve BPD patients and healthy control subjects (p=0.002).
conclusionPDLIM5 mRNA expression did not appear to be a reflection of the efficacy of olanzapine in reducing the manic symptoms of BPD. The significant difference in expression of PDLIM5 mRNA in the peripheral blood leukocytes of treatment-naïve BPD patients versus that of healthy control subjects, however, suggests that it may be a good biological marker for BPD.
