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
Parkinson's disease (PD) is the second most common neurodegenerative disorder. Although most PD cases are sporadic, several loci have been involved in the disease. parkin (PARK) is causative of autosomal recessive juvenile Parkinsonism (ARJP) and encodes an E3 ubiquitin ligase associated with proteasomal degradation. It was proposed that loss of PARK function may lead to the toxic accumulation of its substrates in the brain, thus causing dopaminergic (DA) neuron death. Indeed, the first identified PARK substrate was CDCrel-1, a protein of the Septin family that accumulates in ARPJ brains. Drosophila has been used as a successful model organism to study PD broadly contributing to the understanding of the disease. Consistently, park mutant flies recapitulate some key features of ARJP patients. In this scenario, we previously reported that overexpression of Septin 4 (Sep4), the Drosophila ortholog of CDCrel-1, is toxic for DA neurons and interacts physically with Park, thus suggesting that Sep4 could be a Park substrate in Drosophila. Confirming this hypothesis, we show that Sep4 accumulates in park mutant brains as its human counterpart. Furthermore, we demonstrate that Nedd4, another E3 ubiquitin ligase that may have a role in PD, is functionally related to Sep4 and could be involved in regulating Sep4 subcellular localization/trafficking.
