The final analytic sample included 8,598 participants, 156 of who fell. The risk of fall incidents according to hospitalization time was estimated using logistic proportional hazards models, and restricted cubic splines with four knots model were developed.\nRESULTS: The median hospitalization time was 9.00 (4.00, 17.00) days. The incidence of falls was 1.81% (N = 156). A U-shaped association between the hospitalization time and fall incidence, with an inflextion point of 8 days. We found a decreasing fall incidence as the hospitalization time increased from 0 to 8 days (OR 0.72 [0.62 ~ 0.83], p < .001); beyond 8 days, the fall incidence increased as the hospitalization time increased (OR 1.06 [1.04 ~ 1.09]).", "claims": [{"id": "claim-method", "statement": "The risk of fall incidents according to hospitalization time was estimated using logistic proportional hazards models, and restricted cubic splines with four knots model were developed.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:36177862", "locator": "sections[0] \"Abstract\" paragraph 3", "quote": "The risk of fall incidents according to hospitalization time was estimated using logistic proportional hazards models, and restricted cubic splines with four knots model were developed."}], "state": "complete"}, {"id": "claim-data-access", "statement": "Extra data can be accessed via the Dryad data repository at http://datadryad.org/ with the doi: 10.5061/dryad.16h8j", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:36177862", "locator": "sections[21] \"DATA AVAILABILITY STATEMENT\" paragraph 2", "quote": "Extra data can be accessed via the Dryad data repository at http://datadryad.org/ with the doi: 10.5061/dryad.16h8j"}], "state": "complete"}, {"id": "claim-target-result", "statement": "Hospitalization time was associated with fall incidence in a U-shaped pattern, with an inflection point at 8 days: fall incidence decreased from 0 to 8 days and increased beyond 8 days.", "kind": "qualitative", "target": null, "evidence": [{"asset": "source:pmid:36177862", "locator": "sections[0] \"Abstract\" paragraph 4", "quote": "We found a decreasing fall incidence as the hospitalization time increased from 0 to 8 days (OR 0.72 [0.62 ~ 0.83], p < .001); beyond 8 days, the fall incidence increased as the hospitalization time increased (OR 1.06 [1.04 ~ 1.09])."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "partial", "objective": "Hospitalization time was associated with fall incidence in a U-shaped pattern, with an inflection point at 8 days: fall incidence decreased from 0 to 8 days and increased beyond 8 days.", "steps": [{"id": "read_published_estimate", "order": 1, "name": "Read the published estimate from the source", "kind": "other", "state": "complete", "blocked_on": null, "description": "The claim, method and evidence span published with the source article.", "duration_hours": null, "parameters": {}, "inputs": ["source:pmid:36177862"], "outputs": ["the published estimate and its evidence"], "instruments": [], "reagents": []}, {"id": "obtain_source_data", "order": 2, "name": "Obtain the source data from the named repository", "kind": "data-preparation", "state": "blocked", "blocked_on": "data:accession_absent", "description": "The GEO series accession resolves and its sample accessions are listed.
