LASSO, in which L 1 norm penalization term helps correct both issues, however, suffers other problems: 1) it fails in the p > n case in which the number of features p is larger than that of samples n, and 2) it does not consider the grouping effect and is vulnerable to select only a single feature from a highly correlated desired feature group.
Thus, we conclude that rescue to the pharate stage is a rare event and is vulnerable to background effects.
The subjective nature of self-reported waning of treatment effect is potentially vulnerable to bias as a result of high patient expectation, which constrains its use as part of the challenging multidimensional definition of response.

72 73 74 While an interrupted time series study (where multiple outcome measures are taken before and after the intervention) represents a strong quasi-experimental design, a before-after study compares a single outcome measure before and after the intervention and is vulnerable to distorting effects of pre-existing trends.
