From Neil Fitzsimmons
I’ve just read the article on children poisoned by lead
(19 May, p 16).
How could the researchers justify giving some of the children a placebo, rather than
the drug to flush the metal from their bodies? Lead is a toxic substance. I
thought the ethics on placebos now require researchers not to withhold treatment
that is known to improve the health of the recipient.
