^*The values are given as the number, with the percentage in parentheses. Percentages were calculated by finding the pooled average of the complication of interest/total number of patients in studies reporting complication data. AVBT = anterior vertebral body tethering, and PSF = posterior spinal fusion.

^†Pulmonary complications included atelectasis, pleural effusion, pulmonary edema, and pneumothorax.

^‡Indicates complications mild in nature, reported as “other” or with a frequency of 1 across all studies.
