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
objectiveTo investigate the role of Snitrosylation of protein disulphide isomerasec in methamphetamine (METH)-induced expression of alpha synuclein (αSN) in mouse hippocampus and striatum neurons.
methodsForty C57BL/6 mice were randomized equally into saline control group, METH group, L-NNA (a NOS inhibitor) group and L-NNA plus METH group. All the agents were injected intraperitoneally at an interval of 12 h, and a total of 8 injections were administered; in L-NNA plus METH group, METH was injected 30 min after LNNA in each treatment. Western Blotting was used to detect the expression of nitric oxide synthase (NOS), αSN, PDI and Snitrosylation of protein disulphide isomerase (PDI-SNO) in the hippocampus and striatum of the mice, and nitric oxide (NO) levels were determined using a NO assay kit.
resultsIn METH group, the levels of NOS, PDISNO, αSN and NO all increased significantly compared with those in the control group (P<0.05). Combined treatment with L-NNA and METH, compared with METH alone, resulted in significantly lowered expression of NOS, NO, PDI-SNO and αSN in the hippocampus and striatum of the mice (all P<0.05). No significant differences were found in NOS, NO, PDI-SNO or αSN expressions among METH+L-NNA, L-NNA and control groups (P>0.05).
conclusionMETH induces the activation of NOS and increases NO level to cause the occurrence of PDI-SNO, leading subsequently to increased expression of αSN in mouse striatum and hippocampus. L-NNA, the inhibitor of NOS, can partly relieve nervous system toxicity induced by METH.
