The other is the viewpoint of the study investigator, who observes the disease status with error due to the limitations of the trial design.
To confirm the validity of these patterns and viewpoints, replication of the study is needed particularly in other governorates and other parts of Iraq.
Such recombination events from external sources would strongly affect LD, but have little or no effect on homoplasy and G4 since they introduce what is in effect new polymorphism from the viewpoint of the studied population.
Here, cefadroxil (1, first class), cefepime (2, fourth class), cephalexin (3, first class), cefotaxime (4, third class), cefoperazone (5, third class) and ceftriaxone (6, third class) were selected for the aims and viewpoints of this study.

RCTs are essential to establish quality evidence, although it is generally difficult to conduct RCTs for rare and severe diseases, such as POEMS syndrome, from the viewpoints of designing appropriate study schema and recruiting patients.
From a theoretical viewpoint, the study of this problem for a concrete family of differential equations goes through the calculation of the so-called Lyapunov constants, which gives the necessary conditions for center, see [6, 7].
Also, the study examines the viewpoints of the CHW, but does not include the view of the patients they serve regarding the CHWs.
