Data Sheet 1_When intestinal ulceration meets hematologic malignancies: clinical features

Song Su's dataset contains pooled individual-patient data from a systematic review of 60 studies and 128 patients. It characterizes the clinical features and evaluates mortality for the rare condition of intestinal ulceration with concurrent pancytopenia, often linked to inflammatory bowel disease or Behçet's disease and myelodysplastic syndrome or aplastic anemia. The data was last updated on May 29, 2026.

Use Cases

• Analyzing mortality risk factors based on reported associations with male sex and MDS evolution.
• Characterizing clinical subgroups based on features like sex distribution, trisomy 8 prevalence, and ulcer location.
• Comparing disease presentation and outcomes between Behçet's disease and inflammatory bowel disease patient cohorts.

Strengths

• Data is derived from a systematic review of 60 studies, providing a structured synthesis of evidence.
• Includes individual-patient data for 128 cases, allowing for pooled analysis of a rare condition.
• Mortality rates are quantified, ranging from 31.3% to 44.4%.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 15.6 KB, indicating limited scope.
