Figure 1 PRISMA flow diagram. LGA, large for gestational age
Figure 2 a) Cognitive scores and early-term delivery. The figure displays for each study included in the meta-analysis in the summary statistics (mean, standard deviation, and total sample size) for the cognitive scores and early-term delivery and the standardized mean difference (SMD) and its 95% confidence interval for the continuous outcome. SD, standard deviation; CI, confidence interval
b) Cognitive impairment and early-term delivery. The figure displays for each study included in the meta-analysis in the summary statistics (number of events and total sample size) for the cognitive impairment and early-term delivery and the odds ratios (ORs) and its 95% confidence interval for the dichotomous outcome. CI, confidence interval
c) Low academic performance and early-term delivery. The figure displays for each study included in the meta-analysis in the summary statistics (number of events and total sample size) for the low academic performance and early-term delivery and the odds ratios (ORs) and its 95% confidence interval for the dichotomous outcome. CI, confidence interval
Figure 3 a) Cognitive scores and large-for-gestational-age. The figure displays for each study included in the meta-analysis in the summary statistics (mean, standard deviation, and total sample size) for the cognitive scores and LGA and the standardized mean difference (SMD) and its 95% confidence interval for the continuous outcome. LGA, large for gestational age; AGA, appropriate for gestational age; SD, standard deviation; CI, confidence interval
b) Cognitive impairment / low academic performance and large-for-gestational-age. The figure displays for each study included in the meta-analysis in the summary statistics (number of events and total sample size) for the cognitive impairment or low academic performance and early-term delivery and the odds ratios (ORs) and its 95% confidence interval for the dichotomous outcome. LGA, large for gestational age; AGA, appropriate for gestational age; CI, confidence interval
