the studies might simply have been too small and that their combined data might reveal such associations, at least for some subgroups of women. Today that explanation was dashed as scientists analyzing the combined data also concluded that neither...

they did a good job of assessing patients for their hepatitis C risk and referring them for treatment. The new study did not examine why a higher percentage of patients weren't tested based on risk factors, or what reasons - such as a patient's age ...
