Fig 2. Final adult height prediction accuracy.

The accuracy of adult height prediction was determined by comparing the mean absolute differences between the respective predicted final adult height (FH_PRE) and the true final adult height (FH_TRUE) (Delta Absolute = |FH_PRE − FH_TRUE|). The chronological age at the time of surgery was used to predict the final adult height (FH_{Pre_P}) using the Paley et al. (P) multiplier table, the multiplier according to Sanders–Greulich and Pyle (SGP), and the multiplier according to Sanders–peak height velocity (PHV). Skeletal age was determined using the Modified Fels Knee System (FKS) and the Abbreviated Modified Fels Knee System (aFKS) method. SA at the time of surgery was used to predict the final size (FH_Pre) using two different multiplier tables (SGP) and PHV). Data represent medians with interquartile ranges. Whiskers represent Min to Max values.
