  43. 43. • Forest plot (forest plot shows information from individual studies that went into meta-analysis at a glance. They show the amount of variation between the studies and an estimate of the overall result. • Each square symbol represents a study contributing to metanalysis and the area of square corresponds to the weight of the corresponding study to the metaanalysis. www.dnbpediatrics.com
  44. 44. • The horizontal line through the square shows the confidence interval. The solid vertical line represents no effect. • The diamond represents the overall estimate from the meta-analysis. • The centre of diamond represents the pooled point estimate and the horizontal tips represent the confidence interval. www.dnbpediatrics.com

(a) 'shotgun' scatter, with low correlation, (b) strong positive correlation, (c) strong negative correlation, (d) and (e) low correlation, with very little change in one variable compared with the other, (f) this scatter would generate a spurious high correlation because of the effect of the five points enclosed by the shaded area www.dnbpediatrics.com

  67. 67. Calculation of Target Height and Target Height Centile. Measure the parent’s heights and make a note of their heights on the chart. Calculate the child’s target height (TH) and plot it at 18 years and mark it with an arrow on the growth chart. This represents the child’s projected height and the target range is produced by plotting two points 7.5 cms above and below for a boy and 6 cm above and below for a girl (representing the 10th and the 90th centile for that child) . In the example shown above, the 50th percentile for the general population is the 90th centile for the child measured and the 10th centile for the child is below the 10th centile for the population.
