Co-occurrence network diagram for “the key element of nursing.”

a: Four clusters were extracted for nurses with less than 5 years of experience in neonatal care: (A) supporting a family, (B) personal role in nursing, (C) leaning a skill, (D) nursing technique. b: Five clusters were extracted for nurses with 5 or more years of experience in neonatal care: (A) understanding the patient’s family, (B) supporting the mother, (C) seeing what is possible, (D) protecting patients’ lives, (E) staying with the family.

Text-mining analysis of terms with 100% reliability and a co-occurrence frequency ≥ 2. The number of clusters was confirmed that no nodes are independent. The size of the node indicates the term’s frequency. An edge → is a line connecting a node with other nodes. The direction of the arrow indicates that terms in the bottom node frequently co-occur with terms in the top node. Bidirectional arrows indicate that both terms co-occur frequently and interactively. The thickness of the line indicates a co-occurrence relationship and represents the frequency of co-occurrence.
