CancerSurvival

Description

Cancer survival with ascorbate supplement

Format

A dataset with 64 observations on the following 2 variables.

Survival Survival time (in days)
Organ Breast, Bronchus, Colon, Ovary, or Stomach

Details

In the 1970's doctors wondered if giving terminal cancer patients a supplement of ascorbate would prolong their lives. They designed an experiment to compare cancer patients who received ascorbate to cancer patients who did not receive the supplement. The result of that experiment was that, in fact, ascorbate did seem to prolong the lives of these patients. But then a second question arose. Was the effect of the ascorbate different when different organs were affected by the cancer? The researchers took a second look at the data. This time they concentrated only on those patients who received the ascorbate and divided the data up by which organ was affected by the cancer. They had 5 different organs represented among the patients (all of whom only had one organ affected): Stomach, bronchus, colon, ovary, and breast.
