However, these approaches are limited by the response rate and the variability and subjective nature of the response.
Our study is also limited by the response rate of 25%, however this rate is in keeping with the usual response rates of surveys in general, and reasons for non-response may be explained by apathy, lack of knowledge or disagreement with cannabinoid use for rheumatic conditions.
Conventional therapies (e.g., dacarbazine, interferon-alpha-2b and interleukin-2) are limited by low response rate and demonstrate no overall survival benefit.
Our earlier work on real-time learning suffered from the drawback of the learning time being limited by the response dynamics of the robot's environment.
In the non-coalescent batch the chemical methods were used as the DPM method failed being limited by the response rate of oxygen probes used.
Initially (at pressure <2 MPa), diffusion is limited by mechanical response of the coal matter altering accessibility of the blind pores (Case III-R).
The generalizability of the findings from this study is limited by low response rate.
Numerous follow-up studies are limited by low response and high dropout rates.
Third, several of the surveys reviewed were limited by low response rates [ 15, 20– 20].
