The effect of cotreatment with AR42 and D156844 on surface righting responses of SMNΔ7 SMA mice. SMNΔ7 SMA mice received either 3 mg/kg/d D156844 (gray solid line), 10 mg/kg/d AR42 (orange dashed line, combination of D156844 and AR42 (brown solid line), or vehicle (blue dotted line) beginning at PND04. Behavior responses were also compared against age-matched non-SMA littermates (black solid line). Kaplan-Meier analysis was completed on surface righting success (time-to-event) at PND07 (A) and PND11 (B). The statistical comparisons from the Kaplan-Meier analyses are provided in Table 4.
