Role of Netrin-1 in staging hypoxic ischemic encephalopathy.
Article in Revista da Associacao Medica Brasileira (1992), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThe diagnosis and prognosis of neonatal hypoxic-ischemic encephalopathy are established through clinical evidence and laboratory, imaging, and electrophysiological assessments of the nervous system. Netrin-1 was the first axon guidance molecule identified as a critical component of embryonic development in vertebrates and has a solid chemotropic function for angiogenesis, morphogenesis, cell migration, and axonal guidance. It was hypothesized that Netrin-1 will differ at different hypoxic-ischemic encephalopathy stages.
methodsThis study included 75 hospitalized hypoxic-ischemic encephalopathy newborns and 48 healthy newborns born at the same hospital and followed up only by their mothers. Demographic, laboratory, and Netrin-1 data were evaluated for all hypoxic-ischemic encephalopathy stages.
resultsSerum Netrin-1 concentrations were significantly greater in patients with moderate and severe hypoxic-ischemic encephalopathy who underwent therapeutic hypothermia than in controls and patients with severe hypoxic-ischemic encephalopathy. However, serum Netrin-1 concentrations were not significantly greater in patients with mild hypoxic-ischemic encephalopathy than in controls. In 75 hypoxic-ischemic encephalopathy patients, correlations of Netrin-1 with lactate, uric acid, and lactate dehydrogenase were statistically significant (p=0.0001, 0.008, and 0.043, respectively).
conclusionNetrin-1 significantly increased in moderate and severe patients. Therefore, this marker could be a biomarker for staging hypoxic-ischemic encephalopathy and therapeutic hypothermia and predicting the prognosis of neonatal hypoxic-ischemic encephalopathy patients.
