When should infantile colic resolve by?

Features that suggest infantile colic
baby’s age (colic starts in the first few weeks of life and resolves around 3-4 months of age), the timing of the crying (most often occurs in the late afternoon or evening), and arching of the back (babies often draw their knees up to their abdomen or arch their backs when crying).

Criteria to assess probability of septic arthritis in children, how to calculate and interpret?
Non-weight bearing - 1 point

The probabilities are calculated thus:
0 points = very low risk
1 point = 3% probability of septic arthritis
2 points = 40% probability of septic arthritis
3 points = 93% probability of septic arthritis
4 points = 99% probability of septic arthritis
