Simplified RALE Score: Predictive Validity for COVID-19 Mortality in Vietnam

Between 30 July and 15 October 2021, a retrospective observational study collected data from 105 critically ill adults with confirmed Delta-variant COVID-19 at an intensive care center in Ho Chi Minh City, Vietnam. The dataset likely contains simplified Radiographic Assessment of Lung Edema (RALE) scores derived from chest X-rays, alongside patient outcomes and clinical parameters used to evaluate the score's predictive validity for hospital mortality. The study was authored by Son Ngoc Do and is shared under a CC-BY-4.0 license.

Use Cases

• Training mortality prediction models based on radiographic lung edema scores and clinical parameters.
• Benchmarking the performance of the simplified RALE score against established scores like SOFA and CURB-65.
• Conducting retrospective analyses of clinical outcomes for critically ill COVID-19 patients with the Delta variant.

Strengths

• Dataset is based on a clearly defined cohort of 105 patients with a high mortality rate (79%).
• Study provides specific performance metrics for the RALE score, including an AUROC of 0.747 and adjusted odds ratios.
• Analysis adjusts for a defined set of baseline confounders and mediators, as described in the methods.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects a specific temporal and geographic context (Delta variant in Vietnam, mid-2021), which may limit generalizability.
