Methodological Issues and Evidence of Malfeasance in Research Purporting to Show Thimerosal in Vaccines Is Safe

Table 1

Methodological issues most common in each of the six reviewed studies.

Study reviewed	Methodological issues
Madsen et al. [21]	(i) Changing entrance criteria in ecological studies.; (ii) Withholding important results from the final publication.; (iii) Conclusions not generalizable to the US vaccination schedule due to widely different vaccination schedules and different levels of Thimerosal dosing in other countries.
Stehr-Green et al. [22]	(i) Changing entrance criteria in ecological studies.; (ii) Withholding important results from the final publication.; (iii) Conclusions not generalizable to the US vaccination schedule due to widely different vaccination schedules and different levels of Thimerosal dosing in other countries.
Hviid et al. [23]	(i) Accounting for “person-years” regarding exposure rather than actual exposure levels.; (ii) Conclusions not generalizable to the US vaccination schedule due to widely different vaccination schedules and different levels of Thimerosal dosing in other countries.
Andrews et al. [24]	(i) Accounting for “person-years” regarding exposure rather than actual exposure levels.; (ii) Conclusions not generalizable to the US vaccination schedule due to widely different vaccination schedules and different levels of Thimerosal dosing in other countries.
Verstraeten et al. [25]	(i) Cohort of children too young for followup for an autism diagnosis.; (ii) “Overmatching” phenomena due to too closely matched cases and controls.; (iii) Withholding important results from the final publication.
Price et al. [26]	(i) “Overmatching” phenomena due to too closely matched cases and controls.; (ii) Withholding important results from the final publication.
