As significance testing was not possible for this analysis approach, restrictive cut-offs were used instead.
We developed three search strategies to identify the need to update the recommendations: an exhaustive approach, a restrictive approach, and a PLUS approach.
Aim of the study was to assess the impact of ERAS approach ("fluid restrictive and drainless") on open liver resections for HCC comparing their outcome with open resections in pre-ERAS period and with laparoscopic surgery.
This approach is restrictive in that it does not exhibit a hybrid global model of the designed system, that would though be required for analysis and behavior-checking to take place.
With the trend towards performance-based codes, and innovation in materials and construction, the previous approach was restrictive and so a search was made for alternative means of assessing external claddings for flammability.
However, the closed-model approach requires restrictive assumptions that limit the generality of a model.
Only one previous study of clinical guidelines compared a different type of restrictive approach versus an exhaustive approach [ 9].
Since the latter analysis approach is more restrictive, the results between both analysis approaches also differ.
Fundamental obstacles, identified years ago, remain in place; there are no nationally agreed measures of quality and effectiveness, and restrictive approaches to contracts and payment mechanisms are only gradually being addressed.
Most of these approaches require rather restrictive sample preparations.
