Data for a total of 712 pneumonia patients treated with glucocorticoids, encompassing 127 variables, were downloaded from DRYAD. A total of 368 patients with CTD pneumonia were selected, and 84 variables had missing values of less than 5%. After multiple interpolations to supplement missing values, 37 variables were selected for analysis. These included age, gender, fever, cough, expectoration, chest pain, dyspnea, heart rate, respiratory rate, systolic pressure, diastolic pressure, cyanosis, CAP, bronchiectasia, interstitial lung disease, coronary heart disease, congestive heart failure, diabetes mellitus, anemia, white blood cells, neutrophils, lymphocyte, hemoglobin, platelets, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, serum creatinine, K, Na, oxygen inhalation, high-dose glucocorticoid, immunosuppressant, ganciclovir, sulfanilamide, anti-aspergillus, and anti-pseudomonas. Patients were randomized into two parts, with 247 patients in the training cohort and 121 patients in the validation cohort. The groups were comparable at baseline except for the need for sulfanilamide treatment (Clinical characteristics of patients with CTD pneumonia treated with glucocorticoids or/and immunosuppressants.
