The published form of the VSD analysis first aired at Simpsonwood. Phase I found isolated signals (tics RR 1.89 at HMO A; language delay RR 1.13 at HMO B); Phase II at HMO C found no significant associations; no increased risk for autism or ADHD. An erratum appeared in Pediatrics 2004;113(1):184.
No consistent significant associations were found between TCVs and neurodevelopmental outcomes.
Abstract (Pediatrics 112:1039-48)
The published form of the VSD analysis first aired at Simpsonwood. Phase I found isolated signals (tics RR 1.89 at HMO A; language delay RR 1.13 at HMO B); Phase II at HMO C found no significant associations; no increased risk for autism or ADHD. An erratum appeared in Pediatrics 2004;113(1):184. Inconsistent phase-I signals were not confirmed in phase II — the basis for the authors' and IOM's conclusions.
