2. Treatment and control groups - Wikipedia

   en.wikipedia.org/wiki/Treatment_and_control_groups

   A clinical control group can be a placebo arm or it can involve an old method used to address a clinical outcome when testing a new idea. For example in a study released by the British Medical Journal, in 1995 studying the effects of strict blood pressure control versus more relaxed blood pressure control in diabetic patients, the clinical control group was the diabetic patients that did not ...

   The control group was provided with nutritional supplements, social services, and health care to ensure that these factors did not affect the outcomes of the experiment. [4] All the 111 infants were identified as "high risk" based on maternal education (which was on average 10th grade), family income, and other factors. The teacher-child ratio ...

4. Between-group design experiment - Wikipedia

   The simplest between-group design occurs with two groups; one is generally regarded as the treatment group, which receives the ‘special’ treatment (that is, it is treated with some variable), and the control group, which receives no variable treatment and is used as a reference (prove that any deviation in results from the treatment group ...

   In other examples, outcomes might be measured as lengths, times, percentages, and so forth. In the drug testing example, we could measure the percentage of patients cured. In this case, the treatment is inferred to have no effect when the treatment group and the negative control produce the same results. Some improvement is expected in the ...

6. Average treatment effect - Wikipedia

   en.wikipedia.org/wiki/Average_treatment_effect

   Consider an example where all units are unemployed individuals, and some experience a policy intervention (the treatment group), while others do not (the control group). The causal effect of interest is the impact a job search monitoring policy (the treatment) has on the length of an unemployment spell: On average, how much shorter would one's ...

   Researchers have been making breakthroughs in addiction medicine for decades. But attempts to integrate science into treatment policy have been repeatedly stymied by scaremongering politics. In the early 1970s, the Nixon administration promoted methadone maintenance to head off what was seen as a brewing public health crisis.

8. Propensity score matching - Wikipedia

   en.wikipedia.org/wiki/Propensity_score_matching

   Matching attempts to reduce the treatment assignment bias, and mimic randomization, by creating a sample of units that received the treatment that is comparable on all observed covariates to a sample of units that did not receive the treatment. The "propensity" describes how likely a unit is to have been treated, given its covariate values.
