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
Background: Continued progress in early diagnosis and therapeutic options has contributed to the increased survival of infants with CHD with attendant NDD which is of profound personal and public health significance. Aim: To determine the prevalence and patterns of neuro-developmental problems in children with CHD. Methods: A cross-sectional study consisting of 40 children with CHD attending the Cardiology clinic of University of Nigeria Teaching Hospital (UNTH), as well as 40 age and gender-matched controls with no heart disease recruited from children's outpatient and well-baby clinics. A semi-structured pretested questionnaire was used in documenting socio-demographic data. General and systemic examinations including cardiovascular and central nervous system assessments were done. The echocardiography report from UNTH was reviewed and the type of CHD documented. Neurodevelopmental assessment using The Malawi Developmental Assessment Tool (MDAT) was carried out by the researchers. Data were analysed using IBM Statistical Package for Social Sciences (SPSS 20.0 version). Chi-Square were used to compare age and gender and other demographic variables with Yates correction where appropriate. Bivariate analysis was performed using the type of CHD to identify cardiac lesions associated with NDD. Significant statistical level was set as a p-value < 0.05. Results: Forty subjects and 40 controls aged 6-60months with a male to female ratio of 3:2 were studied. Thirty-seven (92.5%) of the subjects had one or more symptoms of CHD. NDD was noted in 23 (57.50%) children with CHD compared to six (15.0%) of the controls. (χ = 15.63, p< 0.0008). The differences in the number of children with delay across all domains for both groups were (p= <0.001). While 17 (42.5%) patients with CHD had a delay in more than one domain (global delay), none of the control had a delay in more than one domain. The difference in the number of domains with NDD for patients and their controls was statistically significant (p<0.001). Though there is no significant correlation between age (χ Conclusion: NDD was common in children with CHD and a significant number had a global delay when compared with their controls.
