They didn't include any examples of the parallel. This goes over some of the notes:
https://www.theguardian.com/uk-news/2022/oct/13/lucy-letby-p...
> On another, she wrote “I am a horrible evil person” and on another in capital letters: “I AM EVIL I DID THIS,” the jury was told.
> She also wrote on the note: “There are no words”, “I can’t breathe”, “kill myself”, “I haven’t done anything wrong”, “how can I get through it?” and “I am an awful person”. She had also written “No Hope” and “Panic Fear” and then circled in capital letters “HATE”.
Personally, I don't think any of this is strong evidence, since she contradicts herself a bit. But the notes more directly address the murders because she wrote them in response to the accusations. It isn't as vague as a diary entry mentioning a secret.
And as far as I know, they had more evidence in the form of testimony from experts suggesting the babies were killed by injecting them with air, but I'm sure there are reasons to be skeptical of that.
Mainly, I don't know how strongly any statistical "evidence" was presented in court, how much the jury depended on it in their guilty verdict, and how the UK court system works, so I don't have a strong opinion. But I also don't believe a not-guilty person would think to write anything like what she wrote in those notes.
One last thing I'm curious about and have never heard definitive information on is whether babies stopped dying when they took Letby out of the NICU or whatever they call it. I suppose that might still be accounted for in this statistical coincidence element the RSS and other statisticians are discussing.
