Correlation between quality of speech (ALSSS, x-axis) and intellectual abilities (RCPM, a) and language comprehension (TCGB, b) in children affected by the most severe SMA1 a and b forms (blue symbols) and by c form (white symbols). The short-dashed lines indicate the levels of intellectual abilities and language comprehension and the threshold of speech disturbances. The number points seemed lower because some children have the same RCPM and TCGB scores; therefore, some points are overlapped
