here's your shmoop du jour brought to you by aspirin. which you can

00:07

thank for allowing your mother to survive your childhood. now come on clap. [mom frowns, kid yells]

00:12

a researcher wants to know if aspirin can improve memory. in order to avoid

00:16

experimenter bias the researcher has her assistant assigned participant to groups

00:21

so that she doesn't know which participants are in the aspirin group

00:24

and which are in the control group. the participants are also unaware of their

00:28

group and some participants are given aspirin while others are given a placebo.

00:32

what's this procedure known as? and here the people in charge double-blind phase

00:37

1 through 3 and controlled .okay well let's start with all those clinical

00:42

trial answers. or sure mom won't mind. the first stage or phase of a clinical trial

00:46

is when a drug is first tested on humans. which doesn't sound all that safe ,but it

00:52

is because numerous preclinical and phase zero tests come before it .in test

00:58

tubes on animals and through human micro dosing. stage one comes when scientists

01:02

are sure it's safe enough to test as normal doses, but it's also not at all [man peers over glasses at kids]

01:07

with question described so we can cross out b. stage 2 comes after that. while

01:12

stage 1 aims to test safety half-life and tolerability stage 2 is more focused

01:18

on the biological changes caused by the drug. like does the drugs actually have a

01:22

positive effect on the human body .an important stage in clinical trials, sure.

01:27

but not at all to do with what our research was doing. this is followed by

01:31

stage 3 which is focused on the efficacy of the drug within the context of a

01:35

clinical practice this is the gold standard stage which occurs across large

01:39

patient groups in order to see if the drug is ready for the medical market.

01:42

only eighteen percent of drugs that make it to stage two get this far and this

01:47

answer is zero percent of what we're looking for. but what about a controlled

01:52

procedure? the actions of our researcher definitely fit into this answer because [scientist mixes solution]

01:56

it simply describes a series of policies and procedures set in place to ensure

02:00

quality control and accuracy with in a study. unfortunately it's not quite

02:04

specific enough. this leaves us with a the correct answer a double-blind

02:08

procedure describes when both the researcher and the participants are

02:13

blind to which group the participants belong to. it ensures there's no bias on

02:17

behalf of the researcher when making observations and also prevents

02:21

participants from acting a certain way and skewing result. sounds exactly like

02:25

the procedure described. unless you feel like making a bad pun. [kid lines up rats wearing sunglasses]
