one should hide himself/herself under something hard, such as desk, table or even bed and keep away from shelf and cupboard, and never take a lift to go downstairs. If in the open air, find an open place and never
How can one derive hazard ratio from Kaplan-Meier survival plot?doi:10.1136/bmj.g5608BMJ
In the United States (US), the Surveillance, Epidemiology, and End Results (SEER) program is the only comprehensive source of population-based information that includes stage of cancer at the time of diagnosis and patient survival data. This program aims to provide a database about cancer incide...
If we wanted to estimate our survival function attime 30correctly adjusting for left truncation, we would get 2/3, or a 66% survival rate. Without correctly accounting for left truncation, we would include the top individual who has not yet entered the study at time 30, and erroneously calc...
This research proposes new perspectives accounting for the uncertainty on 50% effective rates (ER50) as interval input for species sensitivity distribution (SSD) analyses and evaluating how to include this uncertainty may influence the 5% Hazard Rate (HR5) estimation. We explored various endpoints (s...

At this rate my fish might not be visibly infested for very long. I want to make sure the ich is good and dead, but I also don’t want to dose them any more than strictly necessary. Advice from someone who has treated their fish with Ich-X before would be very much appreciated. ...
In many clnical tials this will be a measure such as survivaL response rate, time to relapse, degree of palliation or a quality of life index. Some- times there is more than one outcome and all are regarded as of equal importance; this is dicussed below. It is customary to start ...
The hazard rate refers to the rate of death for an item of a given age (x). It is part of a larger equation called the hazard function, which analyzes the likelihood that an item will survive to a certain point in time, based on its survival to an earlier time (t). In other word...
