Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Based on variability in age, diagnosis and condition of these patients, the data on enzyme levels and neuropsych testing is extremely difficult to report. For adverse events, see Secondary Outcome Measures #3 and #4.
