Doctors have ended their strike and returned to work amid new hope that a deal over changes to their contracts can be reached before the next planned 48-hour walkout.
Thousands of junior doctors walked out for 24 hours, while around 4,000 operations had to be cancelled.
Two further strikes are planned but talks are expected to resume in an effort to break the stalemate.
Last week, the Department of Health was accused of encouraging an NHS boss to harden the language of a letter to the British Medical Association raising concerns about Tuesday's strike by junior doctors.
Medical director of NHS England, Professor Sir Bruce Keogh's letter raised fears about whether striking junior doctors would be available to respond in the event of a Paris-style terrorist attack.
According to the Independent, emails reveal the letter went through a number of revisions to ensure concerns about the possible impact of a major incident during the walkout were made as "hard-edged" as possible.
The Health Secretary Jeremy Hunt was also given approval of the text, emails between the Department of Health (DoH) and Mr Keogh reveal.
The Department of Health said it was "absolutely right" that ministers insisted on Sir Bruce giving his "independent" view on how the health service would be able to respond.
A spokesman also told the newspaper it was "completely right that the Department expressed a view on communication with the BMA”.
Retired Dr Henry Goodall, who was a junior doctor in 1970, says the current generation are "used to working less hard with fewer hours".
As junior doctors in hospitals across England go on strike for 24 hours today, a junior doctor writes for ITV News on why she is striking.
A government aide was filmed trying to prevent a reporter asking why Jeremy Hunt was not speaking ahead of today's national doctors' strike
