WebThe weighted average of the category-specific rates (with the weights taken from the standard population) provides for each population a single summary rate that reflects the numbers of events that would have been expected if the populations being compared had the same age distribution 1. ...

SMR-weighted Cox proportional hazards models were used to estimate unadjusted and adjusted hazard ratios (aHRs) and 95% confidence intervals for incident development of AMD in the ACE-I group compared to the …
WebConclusions: I argue that the 'target population' epistemology is scientifically irrelevant and so are methods to handle confounders that are founded on this paradigm, namely, standardization, inverse-probability-of-treatment weighting and SMR-weighting. Finally, I propose a simple alternative framework under an indeterministic model of causation. WebThe 143 ScHOLAR-5 patients reduced to an effective sample of 85 patients after SMR weighting vs 86 patients in ZUMA-5. Median follow-up time was 25.4 and 23.3 months for SCHOLAR-5 and ZUMA-5. Median overall survival (OS) and progression-free survival (PFS) in SCHOLAR-5 were 59.8 months and 12.7 months and not reached in ZUMA-5.
Web7 Sep 2024 · Background The standardized mortality ratio (SMR) is often used to assess and compare hospital performance. While it has been recognized that hospitals may differ in their SMRs due to differences in patient composition, there is a lack of rigorous analysis of this and other—largely unrecognized—properties of the SMR. Methods This paper … Small modular reactors (SMRs) are a proposed class of nuclear fission reactors, smaller than conventional nuclear reactors, which can be built in one location (such as a factory), then shipped, commissioned, and operated at a separate site. The term SMR refers to the size, capacity and modular construction only, … See more Economic factors of scale mean that nuclear reactors tend to be large, to such an extent that size itself becomes a limiting factor. The 1986 Chernobyl disaster and the 2011 Fukushima nuclear disaster caused … See more SMRs are envisioned in multiple designs. Some are simplified versions of current reactors, others involve entirely new technologies. All proposed SMRs use nuclear fission with designs including thermal-neutron reactors and fast-neutron reactors See more One study reported that some types of SMR could produce more waste per unit of output than conventional reactors, in some cases more than 5x … See more Small nuclear reactors, in comparison to conventional nuclear power generation plants, offer many advantages due to the flexibility of their modular construction. This flexibility in the modularity of a SMR system allows for additional units to be incrementally added … See more Licensing Once the first unit of a given design is licensed, licensing subsequent units should be drastically simpler, assuming that all units operate identically. Scalability A future power … See more Cooling Conventional reactors typically use water as a coolant. SMRs may use water, liquid metal, gas and molten salt as coolants. Coolant type is determined based on the reactor type, reactor design, and the chosen application. … See more Some proposed SMRs use cooling systems that use thermoconvection – natural circulation – to eliminate cooling pumps that could break down. Convection can keep removing … See more

Web28 Jan 2024 · SMR weighting and overlap weighting allow you to estimate the treatment effect in different populations. SMR weighting allows you to estimate the ATE among those who were treated; overlap weighting will estimate the treatment effect among patients who are most similar to one another. healthy oral hygieneWebadoption of SMR<75-based weighting of small area sub-populations of local authorities had not been given any introductory rationale—only the assertion: The SMR < 75 years is a major driver in the public health formula.
