1. 对每个自变量(因素)赋分 一般情况下,绘制Nomogram时要求每个因素的赋分范围在0-100之间。Nomogram绘制实际上是对上述回归结果的系数做转化后以图形的形式展现出来,即主要是对回归模型拟合系数的转化。 (1)系数转换 对于连续性变量年龄,其范围是10-90,结合表1中估计的各因素的系数,Nomogram的转换公式是: (2)根据...

The prognostic factors for survival among patients with secondary osteosarcoma remain unclear. The aim of this study was to develop a practical nomogram for predicting cancer-specific survival (CSS) in patients with osteosarcoma as a secondary malignancy
Radiomics Nomogram Subcentimeter Pulmonary ground-glass nodules 1. Introduction With the popularization of low-dose computed tomography (LDCT) screening for lung cancer, a frequently reported incidence of small-sized carcinomas appearing as pulmonary ground-glass nodules (GGNs), are increasingly encountered...

PD-L1 expression in bone marrow plasma cells as a biomarker to predict multiple myeloma prognosis: developing a nomogram-based prognostic modelPD-L1 expression is associated with poor prognosis, although this relationship is unclear in bone marrow-derived haematologic malignancies, including multiple ...
aThis suggests that increased association of presbyopia for women is not due to a physiologic difference in accommodation but rather due to other sex differences, such as tasks performed and viewing distances. Age-based correction nomograms for presbyopia should therefore consider these sex differences...
