Evaluating Results

[Kaylz]

This is quite a long winded post so I do apologise but I am interested in how the professional's over the years have evaluated your results? I remember when I was first diagnosed the nurses always told me my standard deviation was good along with my averages etc, how far into this have your teams gone into this with you? I took my meter averages down today and have spent a short time reading a few articles which brought up that the SD must be interpreted into context with the average leading to CV (coefficient of variant) I hadn't heard of this term before despite having a wide knowledge of diabetes that my consultant continually comments and congratulates me on so have any of you? Yes I admit it may be a bit geeky but it gave me something to do while I was cat sitting lol xx

I have never ever had any HCP even mention standard deviation to me Kaylz - first time I ever heard the term was from EDUAD and another chap on my original forum, years ago!

I'm pleased we don't discuss it - mine's never been standard, just deviant!

FWIW, I would have though time in range would be a more useful thing to look at than CV?

this really did make me LOL TW , SD was referred to quite a lot before I started the Libre but these days my meter is never checked only my Libreview but its working well as last predicted hba1c was spot on lab results xx

all could be relevant though as my meter at least doesn't give time in range as a % (I don't think anyway, I'll have to check) of course my Libre does but I'm more talking about before they were rolled out etc xx

I am glad your predicated HBA1C prediction is spot on, mine has been at quite off.
I have not seen any mention of Standard Deviation lately.

In statistical terms, the coefficient of variation is the ratio of standard deviation to mean (average). In other words how to blind you with geek speak! As long as they tell you're good!!! PS I was a very bad statistician for 25 years and I struggled to understand it lol!

I wasn't enquiring to what the CV was as I know that, I was asking if any other members teams had explored their results fully with averages along with SD and CV but thanks

My xdrip receiver app shows for the last 3 months SD of 32.6mg/mol and Relative SD 26.1 but have not got a clue what it means but my Hba1c is 6.0, and 84 percent in range 12percent high 3 percent Low .?

Ideally (but I don't think its taken into consideration much these days with the new fangled stuff available) the CV should be 33% or less meaning the SD should be less than a third of the average glucose, my Libre app doesn't do SD but apparently over 90 days my average is 6.3mmol, 88% in target, 7% 9.1-13.3 and 5% .9 xx

Oh you’re making my brain ache Kaylz ..ha ha. I think the only time this might have been mentioned was during one of the Libre training days, when we were being shown how to interpret all the data. Generally, I think it’s time in target thats looked at for me, maybe it’s different for others. GP nurse (actually new and surprisingly knowledgeable) yesterday didn’t mention it and I’m seeing consultant next month, so we’ll see. If I started going into too much detail I’d never get out of the house🙂

 

[trophywench]

Lisa - I agree entirely with your final words. After I had my first pump, for over a month I seemed to do nothing except record and analyse results - and swore then I'd never do it again cos life's for living and data analysis except in general terms - eg that whatever is obviously far too fatty for my constitution cos all week I've had raging heartburn every time I lie down in bed, so I'll just stop eating it - is simply not on my personal agenda or an area of expertise so I'm best off simply not trying to do it.

May as well ask me to split the flipping atom - clueless! But if you happen to run a multi national company, own an airport, run a Police Force, or run a Database and want any advice about insuring against your legal liability - then I might be able to assist!

I think TIR will gain increasing importance, but it’s only available where you are using sensors... which the vast majority of PWD don’t.

I’ve found SD helpful as a shorthand way of assessing how tightly grouped or wildly scattered my recent BG spot checks have been, and while I haven’t specifically heard about CV, the ‘one third of mean’ was what I worked out to be a good benchmark myself.

By and large my printed results have either been ignored over the years, or just been fuel for not entirely helpful “what caused that rogue reading there” conversations, so I’ve stopped taking them in for the moment. Partly because I’m not very pleased with them currently!

LOL at your last comment Mike!

I had a hypo day yesterday for a change though several of them I didn't feel which is a little oo-er, but to be fair I'd just been sitting still reading/watching TV - when I get up to eg make a cuppa or visit the loo is when I think I'd better test cos I feel odd.

Although I was sitting down using a laptop for 4+ hours solid on Saturday morning (helping a team of 6 registering well over 100 different men online so they could have a PSA bloodtest) I was gobsmacked how knackered I felt when we'd finished. I used to sit at a desk and use a computer all flippin day before I retired, very frequently on the phone and using the puter at the same time.

I just wonder if my body interpreted it as effort - akin the physical effort - and reacted accordingly.

Thats funny i am the complete opposite when sitting at a computer for any length of time my sugar nearly always goes up ,Your job was in a office all day where my job was a toolmaker working to very high tolerances that was very stressful at times that is why i had to give up the job when i got diabetes as you know stress raises your blood sugar ,its the same old thing every diabetic is not the same.

Not everyone responds the same we get people saying opposite happens to them, at the extremes of temperatures.
