What Is My Favorite Clock?

There are so many clocks that nobody really knows how the time is ticking because all the clocks are also quite, quite different. I would say that I only accept a diagnostic marker in clinical practice to use it if the accuracy is at least 80, 90% with a high sensitivity and a high specificity. Do these clocks have that yet? No, we don't know. So what we need in our field is many more studies where we really look at accuracy and looking at not only the area, another curve, but also a sensitivity and specificity and predicted values positive and negative ones.
