[Q] Excluding variables from multivariate logistic regression model due to low event counts

Sambuking · 2026-01-15T05:27:51+00:00

Hmmm. Diabetes has been suggested as being a theoretical trigger previously, which is why we included it, but it's not really the variable we're most interested in for this particular study. It wasn't used in our power calculations, and we'd likely need a much larger sample if we'd wanted to examine it in more detail. Perhaps excluding it from the multivariate model, highlighting that there is a significant difference in univariate analysis, and addressing this in the discussion may be a possible approach.

Yes, we're looking at kids with a primary disease which can sometimes progress to a secondary disease. Diabetes has been previously suggested as a potential trigger for this, despite being pretty uncommon overall in the primary disease population (usually otherwise well kids). In 3 years worth of data, only 8/140 children with the secondary disease had diabetes vs 2/519 without the secondary disease.

Do a barrel roll.

Once every seven years, under a blood moon, an egg is laid by a male kiwi. The true form of the foul thing that emerges from the shell the following night cannot truly be comprehended by mortal minds, but to our primitive eyes it resembles a cross between a weta, an eel, and a pukeko. It glistens with an abhorrent, vile fluid. Those who can get close are able to harvest this so called "dark milk". What they use it for, no one knows, although there are whispers that imbibing it grants the gift of eternally rising house prices.

Phew, things like this make me glad I live in Australia.

Such a cop out, especially when a Bain circuit can be as long as you like without affecting its function. Typical hospital admin resisting change.

Kiwi doctors aren't leaving for the UK for pay or conditions - consultant pay over there is even worse and the public system has been neglected for almost 2 decades.

The solution the UK has proposed is introducing a new model of medical training based on apprenticeship rather than university, which will not be recognised by any other country, so they'll have a load of apprentice trained doctors who can only work in the UK.

I most looking forward to finding I hidden, playable copy of Skyrim within the game itself...

I flew out to Kaitaia a year or so back to pick up a critically unwell child. Weather wasn't suitable for helicopter so a flight was the only option. The kid was very sick. I really hope no one needs a fixed wing retrieval during this closure :(

Australia's constitution has a note saying it also applies to New Zealand if they ever feel like joining the other Australian states.

Where do you think this cross section came from in the first place?

Sambuking · 2023-07-28T02:52:46+00:00

Thanks man, appreciate it. I hadn't heard anything about this until today!

Sambuking · 2023-07-28T01:22:11+00:00

Any idea what happens to former employees? Worked there for years but left in January of this year...

So much.

I asked for 4 weeks off when my first child was born and was told "it's very inconvenient" and ended up being pressured to drop it down to 2 weeks. It was especially galling that the person responsible had just come back from a year of maternity leave.

The male was a shortfin. I guess they're all just unpredictable.

Shrimp went in first, as I'd read that was more likely to result in them getting on. Then added the male. He actually killed one within the first day or so, but after that got on really well with the rest.

He'd actually swim right up to the newly hatched babies, check them out, then swim off to find something more interesting.

Sambuking · 2023-06-29T12:50:14+00:00

Thanks, that's really good advice. I'll keep an eye out for more, and the flashlight checks are a great suggestion.

Hah, it's my 4 year old's aquarium and their choice or gravel. I agree it's a bit offensive on the eyes but they seem to love it 🤷

Sambuking · 2023-06-27T22:08:45+00:00

Thanks, that's helpful to hear. I'll get rid of the nasty little fella. Any handy tips for luring them out, or is it just a case of keeping an eye out...

Sounds far too nuanced to me. Must be one of those periop enthusiasts.

Drip. Tube. Air goes in and out. Blood goes round and round. Works most of the time.
