number remaining at risk

And what about me?

Number remaining at risk Today we are going to do an act of social justice. At least from the point of view of analyzing the results of clinical trials. You will wonder what the post of today is about. Well, everyone knows that when we try a new treatment for a disease, the first thing we want to know is how many patients we cure, for example, of that disease, or how many we prevent from dying from the disease. Imagine that, along with 99 other individuals, you participate in a clinical trial. Ultimately, 2 deaths are prevented with the…

fragility, stability and clinical relevance

Take off your blinders

Fragility, stability and clinical relevance Blinders are pieces that are put over the eyes of some draft animals, such as donkeys or horses. Its purpose is none other than to get the animal to focus only on the road ahead, without being distracted by other things that it could see through its peripheral vision, less important for its task.

Its bark is worse than its bite

Simple correlation One of my neighbors has a dog that is barking the whole damn day. It is the typical dog so tiny it is barely a palm from the ground, which does not prevent it from barking at an incredible wild volume, not to mention the unpleasantness of its “voice” pitch. With these dwarf dogs it is what usually happens, they bark at you like demon-possessed as soon as they see you, but, according to popular wisdom, you can rest easy because the more they bark at you, the less likely they are to bite you.
