@sarahditum “even if the embolisms are discounted and the insulin poisoning deemed tendentious, there is still evidence of severe trauma and overfeeding in some of the babies.” There’s no evidence of this. The overfeeding is speculation from Dr Evans. He read a description of vomit and then

Key section I trimmed from Marnerides testimony in the blog. Restored it because I think it is key to understand. “Yes, the air you refer to is there”. After the meeting *about the X-ray on the 12th* Marnerides looked at the autopsy photos and said ok I can accept that this air

@DPJHodges Our problem is with the fundamentals! We always talk about the fundamentals of the case. A non exhaustive thread @carovinuesa has highlighted many problems with the evidence. Can you even find one post of hers which *isn’t* about the factual evidence.

#LucyLetby . This post concerns the case of one of the insulin babies, Baby F. I would like the opinion of my immunology colleagues and clinical laboratory-based immunologists. Does anyone know the immunoassay used by Liverpool Hospital lab to measure insulin in 2015? In assays

@hughosmond The statistical evidence is just the beginning. It is awful for sure, but the more important point is the medical evidence is now being described as pseudoscience by medical experts. Once you work through the evidence you realise it almost entirely should be excluded. The case

@sarahditum Likewise the “severe trauma” at the time was believed to be because of aggressive CPR by a doctor. Even by that doctor. There’s no evidence whatsoever to suggest that contemporary assessment was incorrect. Except of course… the subjective opinion of Dr Evans.

@DrRJWebb No it’s the weakness of the case against her. I, like many of us, knew what she looked like and had assumed she was guilty based on the coverage of the trial. The evidence presented was so much weaker than its presentation in the media. That is what shifted my opinion.

@DebRoberts22249 The context is the cross examination of Dr Evans during the trial on Tuesday November 1st. Dr Evans confirms that he identified injection of air as the “most likely cause” of a collapse on June 12th, when Letby wasn’t on shift. You can read reporting of it here:

Doctors notice the pattern, patient suddenly deteriorates, doctors can’t explain, digging through cases to find suspicious patterns. Letby or De Berk? They insist the evidence is medical not statistical. It eventually becomes statistical and then it becomes obvious…

Then they tacitly _accept_ the central premise of the defence argument. Only that discolouration is diagnostic of air embolism. What should the jury have inferred from the testimony of the rashes? It’s not diagnostic of air embolism so why should it be allowed in testimony?

I've come to the conclusion that Dr Marnerides, the expert witness pathologist, inadvertently used x-rays taken on 12th June 2015 in his testimony that Letby had injected air into Child C's nasogastric tube, which directly caused the baby's collapse and death on 14th June 2015.

Dr Ward Platt, one of the medical experts behind Angela Cannings’ wrongful conviction told that court that 14% of all SIDS could be attributed to maltreatment. There were thousands of SIDS cases at that point in time. That’s hundreds of baby murders a year in his imagination.

In some threads recently I got the feeling people think this account is run by a stats expert. I’ve never said that but I want to be totally clear: I am not a professor in statistics! I’m a software engineer working in AI. That gives me a background with more maths & stats

@lizhull accuses the New Yorker of cherrypicking because it didn’t look at the weakest evidence of her guilt. Ironically DM ignored the strongest evidence of her innocence It actually did talk about those and highlighted the fact that the British press over indexed on them.

. @privateeyenews today contains another excellent analysis of the Lucy Letby case. It’s ‘behind a paywall’, i.e. you have to buy the magazine to read it. This is how independent journalism survives (ps, has the BBC yet even mentioned doubts about the Letby verdict?).
