Continuing Dialogue on Incentive Bias

Letter to the Editor

Sir: The exchange of Letters to the Editor in the June 1996
(pp. 265-269) issue titled "Incentive Bias?" prompted our response.
We have often wondered whether an incentive bias influences
the Journal not to state in each article printed in a
supplement that a pharmaceutical company has provided financial
support. This acknowledgment is made on the cover of the
supplement, but if reprints of a particular article are distributed,
readers have no way of knowing who provided financial support.
