You would have a difficult time justifying this based on publication rates in mainstream refereed journals.
I've taken quick look at the Britz database for the decade before 2004 (1994 - 2003) and the decade after (2005 - 2014). Now, in the decade before, I did not examine the entries individually because there are so many, so I don't know if there is an equivalent of the LENR Sourcebook in those years or not, but I don't think there is. In the decade after, I have excluded Sourcebook entries, because that is not a mainstream journal.
Also, in the prior decade, I used Britz's keyword res- to identify negative papers, and I think he was quite careful in this assignment up to then. In the later decade, his assignment of res- and res+ has largely lapsed, with many of the years having zero of each, when both highly critical and positive papers were present. So, of the later decade, I assigned the 9 negative papers based on the abstracts. I've cited them all here recently, so it's easy to check if you really think they are negative. If I'm motivated, I may try to examine the individual entires from the earlier decade as well at some stage.
With these qualifications, I found:
The average number of papers per year in the decade before 2004 is 40, and about 10% are negative.
The average number of papers per year in the decade after 2004 is 6.7, and about 13% are negative.
Every single year in the prior decade has more papers than the highest number in the later decade.
So, the rate dropped by a factor of 6 or so, and the fraction of negative papers is about the same, if not a little higher.
Now, as before, this goes through 2014, and so the 35 papers in 2015 are not considered. That's because the purpose is to show that nothing in particular happened (no corner was turned) in 2004, based on refereed literature.
Something *did* happen in 2015, based on the literature, and that something is that Current Science ran a special issue of invited papers in the field. The significance of that can be debated, but it doesn't bear on the question of whether 2004 or 2005 was a turning point. And keep in mind that in the 15 months since, only one rather peripheral paper has been published.
Now, including one more year before and after, changes the averages to 45 and 9, so even in that case, the average rate is still down a factor of 5.
