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 is a neurodegenerative disorder caused by the selective loss of dopaminergic (DA) neurons. In this study, we investigated the protective roles of glial cell line-derived neurotrophic factor (GDNF) and 17β-estradiol (E2) in the neuron cell line MN9D following treatment with 6-hydroxydopamine. This result showed that phosphorylation of protein kinase B (Akt) was significantly increased in treated MN9D cells following co-application of GDNF and E2 compared with only GDNF or E2. Moreover, GDNF enhanced the E2-induced translocation of estrogen receptor α (ERα) from the cytosol to the membrane. Immunoprecipitation experiments showed that the translocated ERα interacted with neural cadherin (N-cadherin) in the membrane. Site-directed mutagenesis of Tyr860 (Y860) in N-cadherin inhibited its interaction with ERα. Combined with the fact that GDNF can stimulate N-cadherin Y860 phosphorylation, we hypothesize that N-cadherin is a novel anchor for ERα, and phosphorylation at Y860 further increases ER's capacity to activate the neuroprotective phosphatidyl inositol-3 kinase/Akt pathway. This study provides evidence that co-application of GDNF and E2 exert important protective effects on DA neurons by increasing the interaction between ERα and N-cadherin.
