Feel free to show why they are invalid.

The Effect of the Taiwan Motorcycle Helmet Use Law on Head Injuries
Wen-Ta Chiu, MD, PhD, Chia-Ying Kuo, MPH, Ching-Chang Hung, MD,
and Marcelo Chen, BA
Quote:
Results. After implementation of the law, the number of motorcycle-related head injuries decreased by 33%, from 5260 to 3535. Decreases in length of hospital stay and in severity of injury and better outcome were also seen. The likelihood ratio χ2 test showed that
severity decreased after the law’s implementation (P< .001). Full helmets were found to be safer than half-shell helmets.
Conclusion. The helmet law effectively decreased the mortality and morbidity from motorcycle-related head injuries.
