On the subject of mil-human losses it has this, which is in rough approximation with other numbers we have seen:
The ensuing war has been a lesson in old-style attrition: an industrial-scale contest of manpower, steel and explosives. Russia is thought to have had over 200,000 casualties, killed and wounded. That is four times the number of Soviet casualties in Afghanistan, a war that lasted for a decade. It is two and a half British armies. More than 20,000 Russians died between December 2022 and April 2023 alone, say American sources, most of them in or around Bakhmut, a previously inconsequential town in eastern Ukraine. Not since Iran’s ruinous siege of Basra in 1987 has an army expended so much, in such a short time, for so little. Ukraine, too, has bled badly. Leaked American intelligence reports in late February suggest that it has suffered over 100,000 casualties itself, including more than 15,000 killed.
So on the KIA+WIA ratio we get Russia 200,000 : Ukraine 100,000, so 2:1 if that 200k is correct
But on the KIA ratio the UA Gen Staff daily update gives 200k as deaths, at least that is how I have followed the number though it seems I may have been wrong in my understanding (now that I compare it with some other stuff below)
If the Russian KIA is 'only' 50k of that 200k then the KIA ratio is Russia 50k : Ukraine 15k, i.e. 3.3:1.
That 50k number accords with this latest study, and some other that are referred to
"Nearly 50,000 Russian men have died in the war in Ukraine, according to the first independent statistical analysis of Russia’s war dead.
Two independent Russian media outlets, Mediazona and Meduza, working with a data scientist from Germany’s Tübingen University, used Russian government data to shed light on one of Moscow’s closest-held secrets — the true human cost of its invasion of Ukraine."

On the KIA: WIA ratio that gives for Russia 50k KIA : 150k WIA, so 1:3 (or 75% chance of surviving if a casualty for a Russian).
On the KIA: WIA ratio that gives for Ukraine 15k KIA : 85k WIA, so 1:5.6 (or 85% chance of surviving if a casualty for a Ukraine).
Those aren't too dissimilar, but what we don't know is the qualitative outcomes.
The overall context is pre war Russian population 143 million and Ukraine 43 million, i.e. 3:1. Where pretty much all of Ukrainian society is making an effort to contribute, but by no means all of Russian society.
