Parvovirus B19 is the cause of thyroid cancer

Background:
The null-hypothesis: human parvovirus B19 is not the cause of human thyroid cancer has been tested.
Methods:
To examine the possible role of parvovirus B19   infection in the aetiology of human thyroid cancer, a literature searched
through the electronic database PubMed was performed. Data were accurately assessed and reanalysed by new statistical methods.
Results: 
The meta-analysis results of this study provide evidence that a parvovirus B19  infection of thyroid tissues and
human thyroid cancer are causal related. The null-hypothesis is rejected.
Conclusion:
The alternative hypothesis: human parvovirus B19 is the cause of human thyroid cancer is accepted (p Value right tailed (HGD)=    1,85004E-05).
