Further, the use of the Internet for enrollment limited the available pool of participants and may introduce a volunteer bias that can affect the validity of the results. Further limitations include self-evaluation of QoL and self-management and possible errors regarding the number of medical checks...

The results show that ERP amplitudes were enhanced in both sexes ofFmr1KO mice across development compared to WT counterparts, with greater enhancement in adult female than adult male KO mice. Gap-ASSR deficits were seen in the frontal, but not auditory, cortex in early development (p21) in f...
A survey-based questionnaire was designed and circulated to accumulate the feedback of small investors in the Pakistan Stock Exchange (PSX). An investment decision making was modeled with disposition effect (DE), herding (HE) effect, and overconfidence (OC) bias, whereas an IT was taken as a...
Two qualitative studies [19,20] were both rated very poor in individual items such as ethics, bias and data analysis. (Appendix 2). All six quantitative studies were rated as good using the Joanna Briggs Institute tool [17]. The sample frame, study subjects, settings of the study and ...
But if there are deviations from these conditions, such as in the case of a Common Factor DGP, multicollinearity acts as an amplifier of bias. I extend Kalnins’ (2018) conclusions by analyzing LPV’s specifications within the common factor context: in this case, incorporating all seemingly ...
Also, postoperative pain therapies were not standardized and could be a potential source of bias in the results. Future research could address these limitations. In conclusion, our results suggest that the SAM and PECS I blocks associated with general anesthesia reduce the occurrence of two ...
The propensity score matching (PSM) method was selected to address and minimize the effects of bias. The least absolute shrinkage and selection operator (LASSO) was applied to Cox multivariable analysis to pinpoint prognostic factors.A comprehensive analysis was conducted on 4102 eligible cases, part...
(4) An ensemble method that amalgamates various prediction models is implemented, aiming to diminish the bias inherent in predictions made by single models, thereby enhancing the overall predictive accuracy of the proposed approach. The remainder of this paper is organized as follows. Section 2 ...
Risk of bias in included studies The risk of bias assessment of each RCT is provided in the Additional file 1: Appendix A for clinical (Additional file 1: Figure S3) and functional (Additional file 1: Figure S4) outcomes. For clinical outcomes, three were rated as “some concerns'' due ...
