Estimating patients' individualized probability of an event of interest is challenging. A must-read book by Gerds and mk clearly explains and guides you when developing and validating prediction models. #predictionmodels #machinelearning

Thanks for comments in The Scientist article Melvin (Ane Appelt & Wendy Woodward MDPhD & Alejandra Manjarrez). One thing that's confusing though: the HR for GARD (close to 1, as you point out, 0.98) is PER UNIT GARD -- this is a continuous analysis. cont. thelancet.com/journals/lanon…

while each patient requires a different amount of physical dose to increase 1 unit of GARD (based on radiosensitivity), imagine a scenario where you dose-escalate a patient by 10 GARD, this would yield a predicted HR = 0.98^10 = 0.82 and so on for other GARD changes

the point of the nomogram in figure 4 is to show this, but we put things back into the ABSOLUTE world of each disease (rather than the abstraction needed for the pooled analysis where everything was RELATIVE).

So many "regression versus machine learning" comparisons are not fair, as they don't allow non-linear trends for predictors in the regression model (eg using splines or polynomials). As such, they only serve to reveal a lack of understanding of good statistical practice

Most analyses that found response a surrogate ignore immortal time bias. Congratulations @sujataCLE and Julio Garcia Aguilar for a rigorous analysis that avoids this common trap.

We can already anticipate the (aging) objections, but the idea of re-branding at least a subset of GS6 seems to be picking up momentum. Feels like the right side of history :) Scott Eggener⁩ ⁦Alejandro (Ale) Berlin⁩ ⁦Andrew VickersHoward Wolinsky⁩ ascopubs.org/doi/full/10.12…
