Publication Bias- A Boon or a Curse

Dear Sir

Maintaining the quality of care certainly requires establishing guidelines
and strict adherence. Even though literature has documented evidence of
bias in adherence to guidelines to an extent of 27% of self reports, no data exist for suspected bias in establishing guidelines(1).

This news establishes a literature landmark. Though suspected by many
but refuted by all, guideline establishment bias should be condemned. This
order is a welcome move by a French court.
