§Information about height, weight and cyanosis at the most recent clinic visit was available for 207 (47%) of 436 children (142/313 [45.4%] children in Group 1; 65/123 [52.8%] children in Group 2) when aged between 8 and 13 years. (NB Data for other parameters are complete).
*Children with height or weight <-2SD below the mean for age represent fewer than 2.5% of the population and are considered to have poor growth or to be underweight respectively.
