Which statistical test should researchers use to estimate or predict degrees of glenohumeral external rotation, as a function of age? 

Based on the study in question 6, the physical therapists are also interested whether these patients seeking physical therapy treatment would also likely seek “complementary or alternative medical treatment”, in other words, whether there is an association between these two variables and how strong the association is. Which statistic should the therapists use?

Based on the study in question 14, researchers also evaluated short-and long-term reduction of knee pain with the numeric pain rating scale (NPRS, scoring 0-10, 0 representing “no pain” and 10 “worst pain ever”) during functional stabilization training (FST) in women with patellofemoral pain. The 31 women were evaluated on the NPRS at baseline, after 8 weeks of intervention, and during a follow-up, 3 months after the intervention. Which statistics did they use?

Comparison of effects of exercise in water, on land, or combined water/land therapy on rehabilitation outcomes of patients with intra-articular anterior cruciate ligament reconstructions revealed that a significant difference in joint diffusion (girth measurements of the knee in inches) was noted after 8 weeks between at least 2 groups. An appropriate statistical test to compare the girth measurements in those three groups is:

Researchers conducted a large study with 150 adults with stroke and 115 able-bodied controls. They verified whether the two groups differed significantly in sex proportions. Which statistical test is appropriate?

In resuscitation of preterm infants, what is the recommended target body temperature range?

For a very preterm infant (< 32 weeks) requiring resuscitation, which of the following is a critical step?

When resuscitating an infant with a congenital diaphragmatic hernia (a special consideration), which of the following is true?

For newborns requiring chest compressions, the compression-to-ventilation ratio in the NRP algorithm is:

When resuscitating a very preterm infant, which of the following is a key consideration?
