Range of treatments proposed in this study (EBPA) (yellow lines) compared to SOSORT Clinical Guidelines (white lines).

		Maximum	Soft Scoliosis Brace
Moderate (21–40°)		Minimum	Half-Time Rigid Bracing	Physiotherapeutic Scoliosis Specific Exercises
	21–30°	Minimum	1. Physiotherapeutic Scoliosis-Specific Exercises
		Maximum	5. Half-Time Very Rigid Bracing
	31–40°	Minimum	3. Half-Time Rigid Bracing
		Maximum	6. Full-Time Very Rigid Bracing
		Maximum	Surgery

		Maximum	Surgery

The Moderate (21–40°) range of scoliosis of the Guidelines is split into two EBPA subgroups (21–30° and 31–40°). For each clinical condition, treatment is proposed by Guidelines and EBPA from a minimum (Min) to a maximum (Max) intensity. The SOSORT Guidelines propose the following intensity progression reported in this table: observation, Physiotherapeutic Scoliosis-Specific Exercises, Soft Scoliosis Brace, half-time (16–18 h per day) rigid bracing, full-time (19–22 h per day) rigid bracing, total-time (23–24 h per day) rigid bracing. In this study, the intensity follows the same progression but with a slight difference: 0 Observation, 1 PSSE (SEAS School), 2 Elastic brace (SpineCor), 3 Rigid brace 18/21 h/d, 4 Rigid brace 22/24 h/d, 5 Very rigid brace (Sforzesco) 18–21 h/d, 6 Very rigid brace (Sforzesco) 22–24 h/d.
