The phrase "are needed for validating" is correct and usable in written English.
It can be used when discussing requirements or prerequisites necessary for the process of validation in various contexts, such as research, software development, or quality assurance.
Example: "The following documents are needed for validating the results of the experiment."
Alternatives: "are required for verification" or "are essential for confirming".
However, genetic analyses and larger studies are needed for validating this hypothesis.
Finally, the studied period was too short to make strong conclusions, and extended data are needed for validating the association found in this study.
Thus, the gap between in vitro and in vivo studies suggests that innovative strategies are needed for validating their safety and efficacy.
In conclusion, the results from this study suggest the potential efficacy of one or more of the PDAs, especially TC, as a dietary supplement for reducing EHEC shedding in cattle, but extensive follow-up studies in cattle are needed for validating their use.
The report emphasized that risk modelling is a valuable tool for improving risk assessment and forecast methods, but loss datasets are needed for calibrating and validating model results, in particular to infer vulnerabilities.
Validated outcome measures are needed for the development and evaluation of new, less toxic therapies for PV.
Validated objective biomarkers are needed for patients with renal cell carcinoma (RCC) to guide patient management and define high-risk populations for follow-up or for therapeutic purposes.
Yet, the GLI reference equations need to be validated for people over 80 years old and more data are needed for this age group [ 21].
To this end, an alternative, yet missing, experimental method would be needed for cross-validating the thin-plate model.
Combining whole-genome resequencing and genome-wide association study (GWAS) would help identify markers for quantitative trait loci (QTL); however, recombination mapping is still needed for validating previously identified markers, identifying new markers, and map-based cloning approaches.
Further studies are needed to validate its efficacy for the treatment of deep wounds.
