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
introductionThe aim of the study was to assess the predicting value of neuromarkers for psychomotor performances of congenital heart defect (CHD) patients before surgery, as until now the researchers only evaluated neuromarkers after the surgical treatment of the CHD.
methodsThis cross-sectional study included children with CHD who did not receive treatment (interventional or cardiac surgery). Psychomotor development was evaluated using the Denver II Screening Test. Blood samples were collected for neuromarkers analysis: neuron-specific enolase (NSE), protein S100 (pS100), brain-derived neurotrophic factor (BDNF), and glial fibrillary acidic protein (GFAP).
resultsWe enrolled 77 children. Patients with CHD experienced more frequent developmental delays compared to healthy children (12-34% in the non-cyanotic group and 26-74% in the cyanotic group). The association between type of CHD and psychomotor impairment was statistically significant (p < 0.0001, RR = 2.604, CI = 2.07-3.26). Neuromarkers value was compared between cyanotic and non-cyanotic groups: NSE and BDNF values were higher in the cyanotic group, respectively, pS100 and GFAP had slightly higher values in the non-cyanotic group. A correlation coefficient of 0.35 (p = 0.023) was obtained between psychomotor development and BDNF level. An AUC of 0.72 was obtained for psychomotor development and BDNF in ROC analysis with the cut-off value of 5895 pg/ml.
conclusionBDNF is showing moderate discriminative ability in predicting psychomotor development outcomes in pediatric patients with CHD.
