Samples are titrated to the end point This means that a chemical is added, drop by drop, to a sample until a certain color change (blue to clear, for example) occurs This is called the END POINT of the titration In addition to a color change, an end point may be reached by the formation of a precipitate or the reaching of a specified pH An end point may be detected by the use of an electronic device such as a pH meter
What a clinical trial is trying to measure or find out In essence, the goal of the trial It is scientifically very important that the goals for clinical trials be selected and clearly defined in advance Typical end points include measurements of Toxicity, Response Rate, and Survival
The last data point based on the timeframe requested by a radar data user It is not necessarily the last radar hit for a target of interest Also see Start Point
Where a titration is stopped The point in a titration at which there is a sudden change in a physical property, such as indicator color, pH, conductivity or absorbance The final value when titrating a solution
- What a clinical trial is trying to measure or find out; the goal of the trial Typical end points include measurements of toxicity, response rate, and survival
