An Empirical Assessment of the Cost of Dichotomization of the Outcome of Clinical Trials
We have studied 21 435 unique randomized controlled trials (RCTs) from the Cochrane Database of Systematic Reviews (CDSR). Of these trials, 7224 (34%) have a continuous (numerical) outcome and 14 211 (66%) have a binary outcome. We find that trials ...

Explain your username: Was working with Johan Giesecke and Johan Carlsson at Smittskyddsinstitutet. Obviously, I was third in "rank" among the Johans and the reference to the 16th century Swedish King Johan III was then also obvious. At one point johaniii was taken so I switched to iiijohan.

Use continuous data. That's the lesson of the day; people are capable of dealing with it. If you give people outs to using continuous data; you make your models much less clinically useful. #medsky

Hi, can you help me? I want to develop a model that makes risk predictions. Use logistic regression. Can I use some more modern techniques, like AI? Use a neural network with single non-hidden feed forward layer that outputs to a single dimension using a sigmoid activation function.
