Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This research is an in vitro cell experiment. All the relevant index data of the experiment were uniformly collected and recorded on-site by our research group in our laboratory. All original experimental data, images and statistical results are promptly archived and preserved, and a dedicated experimental data ledger is established. Data entry is double-checked by two people to ensure its authenticity, completeness and traceability. Experimental data and original data are properly retained in accordance with the management norms of scientific research archives, strictly kept confidential, and are only used for academic research on this topic. They are not disclosed to the outside or misappropriated for other purposes.
