The phrase "a rigorous classification of" is correct and usable in written English.
It can be used when discussing a detailed and systematic categorization of items, concepts, or phenomena in a specific field of study.
Example: "The research paper provides a rigorous classification of various species based on their genetic characteristics."
Alternatives: "a thorough categorization of" or "an exhaustive classification of".
The present study, even though used a retrospective design, followed a rigorous classification of the class II patients and selected a well-matched control group.
It implements a rigorous classification of the types and purposes of all expenditures and of all the actors in the health system, and provides a complete accounting of all spending for health, regardless of the origin, destination, or object of the expenditure [23].
While not all datasets allow a rigorous classification of abuse or dependence, opioid users are identified in the data by virtue of the health or treatment consequences of their opioid abuse, dependence, or poisoning, and are thus all potential candidates for drug services [ 20, 21].
By use of space-frequency domain coherence theory, we establish a rigorous classification for the electricfield vector to oscillate in one, two, or three spatial dimensions.
The establishment of a rigorous classification scheme for the various families of the extended LHC protein superfamily was based on primary and secondary sequence information from a comprehensive database search.
Moreover, the mtSNPs allow for a more rigorous classification of mtDNAs into hgs due to the (average) low mutation rate characterizing these SNPs compared with the mutation rate in the control region [33].
The Adriatic has two types of rather special sea bottoms, difficult to arrange in a rigorous classification but very common in the Mediterranean, namely, inlet-derived sediments and heat-altered sediments of the sea bottom proper.
The HEMO Study provided an opportunity to assess the extent to which diabetes influences survival in prevalent hemodialysis patients since the study has a prospective follow-up, careful characterization of the severity of comorbid conditions, rigorous classification of the cause of death, and used diabetes as a stratification variable.
The IPS is a structured approach based on two prominent concepts: the rigorous classification of process behaviors and control tasks, and the use of standard performance indices to identify behaviors and schedule control activities accordingly.
Strengths of our study include the large sample size, with a number of stroke cases similar to that of studies on candidate genes in a recent meta-analysis, the genetic homogeneity of the populations, and the rigorous classification of stroke cases and controls.
Rigorous classification of assays and targets in bioassay databases has been a continuing challenge, with efforts ongoing by the projects BAO and BARD.
