1 · What the graph read from it

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.

2 · The registry

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

Perinatal asphyxia is a major contributor to neonatal morbidity and mortality, particularly among preterm infants, whose brains are highly vulnerable to hypoxic-ischemic injury. The germinal matrix (GM), owing to its vascular fragility and high metabolic demand, is especially susceptible in this context. This study analyzed 118 germinal matrix samples from neonates, stratified into three groups according to gestational age-Extremely Preterm (EP), Late Preterm (LP), and Term (T)-to investigate the immunopositivity of hypoxia-inducible factor 1-alpha (HIF-1α) and brain-derived neurotrophic factor (BDNF), correlating these findings with gestational age, the presence of asphyxia, neuronal injury, and survival time. BDNF expression showed a positive association with postnatal survival in neonates without neuronal injury (ρ = 0.309;
