The number of French papers published in the US journals decreased after the French veto, with an almost symmetrical increase in the number of French papers published in the UK journals (table). For most other EU countries, the change over time in the number of papers published in US or UK journals was in the same direction for both these groups of journals. We found a similar pattern for Belgium to that for France, whereas we found a reverse pattern for Germany, and to a lesser extent for Denmark...
Although Germany supported the French position, the number of German papers in the US journals increased over the two periods. This finding is not contradictory with a specific boycott of French scientific output as no marked anti-German protest arose in the United States.
Although editorial decisions in medical and scientific journals should be based solely on scientific criteria (footnote 1), this is not always so (footnote 2), and the country of origin of submitted papers may influence reviewers' decisions (footnote 3), but little is known about the influence of major political events on such decisions. Although no definite conclusion can be drawn from the present findings, they suggest that the rumour of a US boycott of French scientific output is not totally groundless.
