| Primary | Radiographic Global Impression of Change (RGI-C) Global Score at Week 40 | Week 40 | Changes in the severity of rickets and bowing were assessed using a disease specific qualitative RGI-C scoring system. The RGI-C is a 7-point ordinal scale with possible values: +3 = very much better (complete or near complete healing of rickets), +2 = much better (substantial healing of rickets), +1 = minimally better (i.e., minimal healing of rickets), 0 = unchanged, -1 = minimally worse (minimal worsening of rickets), -2 = much worse (moderate worsening of rickets), -3 = very much worse (severe worsening of rickets). |
| Secondary | Percentage of Participants With a Mean RGI-C Global Score ≥ +2.0 (Responders) at Week 40 | Week 40 | RGI-C responders are defined as participants with a mean RGI-C global score \>= +2.0. The RGI-C is a 7-point ordinal scale with possible values: +3 = very much better (complete or near complete healing of rickets), +2 = much better (substantial healing of rickets), +1 = minimally better (i.e., minimal healing of rickets), 0 = unchanged, -1 = minimally worse (minimal worsening of rickets), -2 = much worse (moderate worsening of rickets), -3 = very much worse (severe worsening of rickets). |
| Secondary | Percentage of Participants With a Mean RGI-C Global Score ≥ +2.0 (Responders) at Week 64 | Week 64 | RGI-C responders are defined as participants with a mean RGI-C global score \>= +2.0. The RGI-C is a 7-point ordinal scale with possible values: +3 = very much better (complete or near complete healing of rickets), +2 = much better (substantial healing of rickets), +1 = minimally better (i.e., minimal healing of rickets), 0 = unchanged, -1 = minimally worse (minimal worsening of rickets), -2 = much worse (moderate worsening of rickets), -3 = very much worse (severe worsening of rickets). |
| Secondary | RGI-C Global Score at Week 64 | Week 64 | Changes in the severity of rickets and bowing were assessed using a disease specific qualitative RGI-C scoring system. The RGI-C is a 7-point ordinal scale with possible values: +3 = very much better (complete or near complete healing of rickets), +2 = much better (substantial healing of rickets), +1 = minimally better (i.e., minimal healing of rickets), 0 = unchanged, -1 = minimally worse (minimal worsening of rickets), -2 = much worse (moderate worsening of rickets), -3 = very much worse (severe worsening of rickets). |
| Secondary | Change From Baseline in RSS Total Score at Week 40 | Baseline, Week 40 | The RSS system is a 10-point radiographic scoring method that was developed to assess the severity of nutritional rickets in the wrists and knees based on the degree of metaphyseal fraying, cupping, lucency, separation, and the proportion of the growth plate affected. Scores are assigned for the unilateral wrist and knee X-rays deemed by the rater to be the more severe of the bilateral images. The maximum total score on the RSS is 10 points and the minimum score is 0, with a total possible score of 4 points for the wrists and 6 points for the knees (the total score is the sum of the wrist and knee score). Higher scores indicate greater rickets severity. |

Scores are assigned for the unilateral wrist and knee X-rays deemed by the rater to be the more severe of the bilateral images. The maximum total score on the RSS is 10 points and the minimum score is 0, with a total possible score of 4 points for the wrists and 6 points for the knees. Higher scores indicate greater rickets severity. |
| Secondary | RGI-C Long Leg Score at Week 40 | Week 40 | Changes in the severity of lower extremity skeletal abnormalities, including genu varum and genu valgus, were assessed using a disease specific qualitative RGI-C scoring system. The RGI-C is a 7-point ordinal scale with possible values: +3 = very much better (complete or near complete healing), +2 = much better (substantial healing), +1 = minimally better (i.e., minimal healing), 0 = unchanged, -1 = minimally worse (minimal worsening), -2 = much worse (moderate worsening), -3 = very much worse (severe worsening). |

| Secondary | Change From Baseline in Height-For-Age Z-Scores to Week 40 | Baseline, Week 40 | Recumbent length/Standing height z scores are measures of height adjusted for a child's age and sex. The Z-score indicates the number of standard deviations away from a reference population (from the Centers for Disease Control \[CDC\] growth charts) in the same age range and with the same sex. A Z-score of 0 is equal to the mean with negative numbers indicating values lower than the mean and positive values higher. Higher Z-scores indicate a better outcome. |
| Secondary | Change From Baseline in Height-For-Age Z-Scores to Week 64 | Baseline, Week 64 | Recumbent length/Standing height z scores are measures of height adjusted for a child's age and sex. The Z-score indicates the number of standard deviations away from a reference population (from the CDC growth charts) in the same age range and with the same sex. A Z-score of 0 is equal to the mean with negative numbers indicating values lower than the mean and positive values higher. Higher Z-scores indicate a better outcome. |
| Secondary | Change in Growth Velocity Z Score From Baseline to Week 40 | Baseline, Week 40 | A growth velocity Z score was calculated based on Tanner's standard. The Z score indicates the number of standard deviations away from a reference population (from Tanner's standard) in the same age range and with the same sex. The baseline growth velocity was calculated for participants who had data available from within 1.5 years prior to baseline. The Week 64 growth velocity was calculated using data between baseline and Week 64. The mid-point of the age interval was used to locate the closest reference age provided by Tanner's Standard. Children with a mid-point age under 2.25 years were excluded, because younger ages are not available in Tanner's standard. To smoothly transition from recumbent length to standing height, 0·8 cm was subtracted from recumbent length before pooling with standing height. A Z score of 0 is equal to the mean with negative numbers indicating values lower than the mean and positive values higher. Higher Z scores indicate a better outcome. |
