Risk prediction models for discrete ordinal outcomes: Calibration and the impact of the proportional odds assumption

Michael Edlinger et al.

Summary: Calibration of risk prediction models is crucial, especially for ordinal outcomes, but research in this area is limited. This study compared calibration measures for risk models predicting discrete ordinal outcomes, and found that multinomial logistic regression generally provides more accurate risk estimates. The study also showed that the proportional odds assumption impacts calibration and overfitting.

Pre-diagnosis lifestyle, health history and psychosocial factors associated with stage at breast cancer diagnosis - Potential targets to shift stage earlier

Qinggang Wang et al.

Summary: This study aimed to evaluate the associations between various potential risk factors and the stage at diagnosis of breast cancer in women from Alberta, Canada. The results revealed that older age at diagnosis, higher household income, parity, smoking, sun exposure during high ultraviolet times, having a mammogram, and high daily protein intake were protective factors, while comorbidity, current stressful situations, and high daily caloric intake increased the risk of later stage diagnosis. Cancer prevention programs targeting high-risk groups, such as those with comorbidities, non-smokers, and younger women eligible for breast cancer screening, may help to lower the stage at diagnosis of breast cancer.

VALUE OF ASSESSMENT OF DIFFERENT NEOPLASIAS IN THE ADNEXA IN THE DIFFERENTIAL DIAGNOSIS OF MALIGNANT OVARIAN TUMOR AND BENIGN OVARIAN TUMOR: A META-ANALYSIS

Xiang Yue et al.

Summary: This study evaluated the accuracy of the ADNEX model in differentiating malignant and benign ovarian tumors and determined the optimal cutoff value for diagnosis. The results showed that the ADNEX model had high sensitivity and specificity in distinguishing between malignant and benign ovarian tumors, and it was particularly effective in diagnosing benign and stage II-IV ovarian tumors.

Can National Registries Contribute to Predict the Risk of Cancer? The Cancer Risk Assessment Model (CRAM)

Dorte E. Jarbol et al.

Summary: The study aimed to develop a predictive model based on Danish administrative registers for automated identification of individuals at risk of any type of cancer. Numerous predictive risk factors were identified, with age being the strongest predictor. The models showed modest accuracy in predicting cancer risk and require further investigation before clinical application.

Methodological guidance for the evaluation and updating of clinical prediction models: a systematic review

M. A. E. Binuya et al.

Summary: This article provides an overview of methodological guidance for the evaluation and updating of clinical prediction models. Key aspects for validation include assessing statistical performance using measures of discrimination and calibration. Recent papers suggest using decision-analytic measures to assess the impact or usefulness in clinical decision-making. Commonly recommended methods for model updating include recalibration, revision, and extension. Further guidance is needed for newer types of updating and machine learning-based models.

Health-Related and Behavioral Factors Associated With Lung Cancer Stage at Diagnosis: Observations From Alberta's Tomorrow Project

Michelle L. Aktary et al.

Summary: This study used data from adults in Alberta, Canada to examine factors associated with lung cancer stage at diagnosis. The study found that a history of sunburn in the past year was protective against late-stage lung cancer diagnosis, while a higher number of prostate specific antigen tests and total recreational physical activity were associated with reduced and increased odds of late-stage lung cancer diagnosis, respectively.

Missing Data in Prediction Research: A Five-Step Approach for Multiple Imputation, Illustrated in the CENTER-TBI Study

Benjamin Yael Gravesteijn et al.

Summary: Missing data is common in medical research, especially in acute diseases like traumatic brain injury. Imputation is widely accepted as an appropriate way to deal with missing data in statistical modeling. A five-step approach centered around imputation is proposed for handling missing data in prediction modeling studies, aiming to optimize statistical analysis and interpretation.

Estimating the risk of malignancy of adnexal masses: validation of the ADNEX model in the hands of nonexpert ultrasonographers in a gynaecological oncology centre in China

Ping He et al.

Summary: The study validated the diagnostic accuracy of the IOTA ADNEX model in the preoperative diagnosis of adnexal masses in a gynaecological oncology centre in China. The model showed excellent performance in differentiating benign and malignant adnexal masses, but had difficulty distinguishing between BOT and stage I OC, as well as BOT and ovarian metastases.

Clinical Data Prediction Model to Identify Patients With Early-Stage Pancreatic Cancer

Qinyu Chen et al.

Summary: This study evaluates a machine learning approach to identify patients with early-stage pancreatic cancer from electronic health records. The predictive model constructed using patient data showed promise in early detection of pancreatic cancer, potentially impacting high-risk patients and being paired with imaging or biomarker screening tools.

Predictors of CRC Stage at Diagnosis among Male and Female Adults Participating in a Prospective Cohort Study: Findings from Alberta's Tomorrow Project

Monica Ghebrial et al.

Summary: Colorectal cancer is a major cause of morbidity and mortality in Canada. This study found that differences in sex play a role in the stage at which CRC is diagnosed, with different factors influencing diagnosis stage for males and females. Understanding these differences can help target cancer prevention programs more effectively.
