The extension enrolled 13 participants who had completed the parent trial; all received deramiocel, and 9 continued to month 60. The absence of a concurrent randomized control group, selection of prior-trial completers, and attrition limit causal interpretation. External-comparator analyses depend on modeling and cross-study comparability. The five-year comparator estimate is a projection, not an observed five-year randomized comparison. The earlier poster described the 3.46-point and 7.19-point estimates as yearly declines, whereas the later presentation labels them as three-year modeled changes; these descriptions should not be combined as if they used the same time scale. Off-treatment comparisons used linear interpolation, and analyses were exploratory and unadjusted for multiplicity.
