It is “completely incorrect” says @Hilary_Cass

- You may have seen a version of this tweet, which seems to claim that energy costs in the UK are many times more expensive than the rest of Europe - over four times as much as the next two countries, Belgium and France. Here’s why that tweet is wildly misleading. A thread 🧵1/10
- Replying to @BBCMoreOrLessDr Cass told us she was “angry” that misinformation was spreading about the review. "Adults who deliberately spread misinformation about this topic are putting young people at risk, and in my view that is unforgivable." 5/8

- Replying to @BBCMoreOrLessTaken together, they looked at 103 scientific papers. They found only two - or around 2% - were high quality. But they also included the moderate research in their conclusions. 3/8

- Replying to @BBCMoreOrLessAround 40% - 43 papers - was considered of low quality, and so was not used to form the systematic reviews' conclusions. 4/8
- Replying to @BBCMoreOrLessCass commissioned @UniOfYork to produce systematic reviews to analyse the available research on puberty blockers and hormone treatment. adc.bmj.com/content/early/… adc.bmj.com/content/early/… 2/8
- Replying to @BBCMoreOrLessCass: "We're certainly not saying that no-one is going to benefit from these treatments, and I myself have spoken to young people who definitely do appear to have benefited." 6/8
- This week on More or Less, we’ve been digging into the numbers behind rising energy bills. What’s driving the increase in the price cap? Let’s start with the profits made by the people who sell us our energy - the energy suppliers. 1/13
