We have a small child here, I mean I don't know whether... So while they're asking, how are you not talking? Yeah, so Becky will show you in our updated design. So this new design has got three slits in it and when it's threaded it looks like that and it just means that it's a little bit more stable. So there's not so much movement, so if you've got a wriggling child it's much easier to take a stable measurement. We've also made it thicker, so you can see on the UNICEF one it's much thinner and there's been some discussion that that can lead to the over compression of skin and it can lead to a mis-measurement. We've also made the material a bit thicker, so it's a bit more robust and less likely to break. And you can see some of the other versions are much thinner and they can crumple up a little bit and are prone to tearing. We also used a much thicker strap material and that actually led to us discovering that the thickness of the strap material affects the measurement accuracy of the tool because you'll talk a bit more about that. Yeah, so during the process of validating the ruler itself so we used these standardised tubes, so they all have measurements written on them. So we were validating the strap and we noticed that consistently it was over-measuring the true value and this was in both the UNICEF version and the UNIMU version. So you think you're going to get more accurate measurements, that's what this is all about? Yeah, we thought that potentially it was due to the thickness of the strap material itself. So to test this we readjusted the ruler on the UNIMUwack and decided to do a standardisation exercise. So it's basically just a comparison of the performance of the UNIMUwack versus the UNICEF strap to see if this would affect the accuracy. Okay, well we've got a live test going on here. Esther, how's your little one doing? He's not happy about it. He's okay. But he said me does not look malnourished. He's not malnourished. He's so worried I gave him food straight away. So is this easier to use Esther than the previous one? Harder to use? What's your feeling? Well, if you have a moving child it's still be difficult but I think it's very user-friendly. Does it slide easily? I can say it's easier to read in a way. It's got this red mark there, and the two holes are on it. It's larger, so that's good. It's easier to put. So now I think it's very user-friendly. Thanks very much and thank you very much. Thank you very much. Great. Any final words? Yeah, well just to say that the results of this comparison showed that actually the Unimio extract was more accurate, so it was consistently measuring the true value more than the UNICEF version, and that it was more sensitive than the UNICEF version. So what do UNICEF think about all of this? So we haven't received formal feedback, but yeah, that's pending. I mean Chrissy, this looks actually very important because if I look at the table that's just here, I mean it's one thing to say a sort of a measurement error in terms of millimetres or centimetres, but if I look here what you're saying to me is that with the UNIMOAC, three children or three tubes I guess here that should have been red which is severe malnutrition or misdiagnosed as yellow, whereas on this side with the UNICEF strap, 17 children who should have been in the red or severe malnutrition category were misdiagnosed as yellow. What does that mean to you? Yeah, exactly. I mean I think that it has the potential to impact on services for children who actually need the nutritional support, potentially being denied access to that due to the mis-measurement in the strap. So a revolution? Potentially. So we haven't tested it in the field yet. When are you going to do that and where? So tentatively, probably within the next six months or so, and we're still deciding on a site for... But it'll probably be in the Sahel or...? We don't know, tentatively south Sudan, but yeah. Good luck, it looks cool, and let us know what UNICEF think.
