HTRA2 variations in Taiwanese Parkinson's disease.
Article in Journal of neural transmission (Vienna, Austria : 1996), 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Mutations in HTRA2 have been reported to associate with Parkinson's disease (PD). This study investigates if the genetic variants in HTRA2 contribute to Taiwanese PD. HTRA2 cDNA fragments from 80 patients with early-onset PD (onset ≤50 years) were sequenced. The identified variants were further examined for a cohort of PD and ethnically matched controls. A novel heterozygous R36W was identified in one early-onset and two late-onset PD patients, which was absent in 606 normal controls. The clinical features and 99mTc-TRODAT-1 SPECT image of the early-onset patient carrying R36W were similar to that of idiopathic PD. The R36W mutation of the patient was inherited from his mother whose SPECT revealed asymmetric reduction of 99mTc-TRODAT-1 uptake in the left striatum, suggesting that the defect of the nigrostriatal pathway may be attributable to the R36W in this family. Protein subcellular fractionation further revealed that R36W affected the processing of the proprotein after transport into mitochondria. Although the functional assays are promising, a larger cohort of both cases and controls should be screened to clarify the role of R36W in Taiwanese PD pathogenicity.
