Q

PPSV23 vs PCV13

A

PPSV23: Contains 23 polysaccharides. Induces a relatively T-cell-independent B-cell-response that is less affective in young children and the elderly.

PCV13: contains 13 polysaccharides that have been covalently attached to inactivated diphtheria toxin protein. Induces a T-cell-dependent B-cell response resulting in improved immunogenicity due to the formation of higher affinity antibodies and memory cells

Statistical modeling for example multi variant analysis is to control

A

Confounding

233
Q

The null value for correlation coefficient

234
Q

Confounding versus effect modification

A

Can be elucidated via stratification:
If stratification leads to no significant difference in the stratified groups then it is confounding.
Conversely if there is a significant difference between the two groups then the variable is an effect modifier.

235
Q

When is the odd ratio a good approximation of relative risk in a study

A

When the disease is rare

236
Q

The medication reconciliation intervention most likely to result in a decrease in adverse drug events and healthcare utilization

A

Pharmacist directed interventions

High-risk patients targeted interventions

237
Q

Respondent bias

A

Is present when the outcome is obtained by the patient’s response and not by objective diagnostic methods
For example migraine headache

238
Q

The effect of sample size on confidence interval

A

Smaller sample size=increased CI=decreased power

Larger sample size=decreased CI=increased power

239
Q

Hazard ratio

A

The ratio of an event rate occurring in the treatment group compared to an event rate occurring in the non-treatment group. A ratio less than 1 indicates that the treatment group had a significantly lower events rate while values greater than 1 indicate that the treatment group had a much higher event rate.

240
Q

Factorial design

A

Involves two or more experimental interventions, each with two or more variables that are studied independently

241
Q

Susceptibility bias

A

When is the treatment regimen selected for a patient depends on the severity of the patient’s condition, a form of selection bias known as susceptibility bias can result (confounding by indication)

242
Q

Intention to treat analysis

A

To avoid selection bias in studies patients are randomly assigned to treatments to minimize potential confounding variables. many studies also perform any intention to treat analysis to deal with the selection bias. An I TT analysis compares 2 initial randomized treatment groups (the original intention) regardless of the eventual treatment, to avoid counting crossover patients.

243
Q

As-treated analysis

A

Conversely to ITT, as-treated analysis compares the groups based on the actual treatment received. An as-treated analysis is performed to gauge the effectiveness of the treatment itself, with less regard for potential confounders.

244
Q

Drugs associated with photosensitivity reaction
