Quantitative investigation of inappropriate regression model construction and the importance of medical statistics experts in observational medical research: a cross-sectional study

  title={Quantitative investigation of inappropriate regression model construction and the importance of medical statistics experts in observational medical research: a cross-sectional study},
  author={Masanori Nojima and Mutsumi Tokunaga and Fumitaka Nagamura},
  journal={BMJ Open},
Objective To investigate under what circumstances inappropriate use of ‘multivariate analysis’ is likely to occur and to identify the population that needs more support with medical statistics. Study design and settings The frequency of inappropriate regression model construction in multivariate analysis and related factors were investigated in observational medical research publications. Results The inappropriate algorithm of using only variables that were significant in univariate analysis… 

Systematic review of education and practical guidance on regression modeling for medical researchers who lack a strong statistical background: Study protocol

This review will provide a basis for future guidance papers and tutorials in the field of regression modeling which will enable medical researchers to interpret publications in a correct way, to perform basic statistical analyses in acorrect way and to identify situations when the help of a statistical expert is required.

This report highlights the global and critical steps to be reported in the statistical analysis of grants and research articles and provides clarity and the importance of understanding study objective types, data generation process, effect size use, and evidence-based biostatistical methods use through several thematic frameworks.

Misuse of Regression Adjustment for Additional Confounders Following Insufficient Propensity-Score Balancing.

The bias in the Rotterdam Tumor Bank is empirically illustrated, in which strong confounders distort the association between chemotherapy and recurrence-free survival.

Pain and numbness one month after carpal tunnel release predict patient-reported outcome measures at sixth months

It is found that pain and numbness, evaluated with VAS 1 month post-surgery had significant correlations with QDASH, Hand20, SSS and FSS 6 months after surgery.

Histometabolic Tumor Imaging of Hypoxia in Oral Cancer: Clinicopathological Correlation for Prediction of an Aggressive Phenotype

In OSCC, FDG-PET-derived metabolic tumor parameter SUVmax serves as a surrogate marker for hypoxia and can be used to predict tumor aggressiveness, with more invasive phenotypes and poorer local control.

The prognostic utility of pre‐treatment neutrophil‐to‐lymphocyte‐ratio (NLR) in colorectal cancer: A systematic review and meta‐analysis

While more standardised and rigorous large-scale studies are needed before high NLR can be fully assessed as an independent predictor of CRC progression and outcome, the data suggest that it may be used to highlight individuals with tumour-promoting inflammatory context.

Letter: microwave vs radiofrequency ablation for hepatocellular carcinoma within the Milan criteria—Authors’ reply

Not only variables with P value less than 0.1 in univariate analysis, but also variables (tumour size, tumour number, and treatment option) with great clinical importance were introduced into the multivariate analysis regardless of their P values in the univariate Cox model.



Multivariable prognostic models: issues in developing models, evaluating assumptions and adequacy, and measuring and reducing errors.

An easily interpretable index of predictive discrimination as well as methods for assessing calibration of predicted survival probabilities are discussed, applicable to all regression models, but are particularly needed for binary, ordinal, and time-to-event outcomes.

If a trial is to be well designed, and the conclusions drawn from it valid, a thorough understanding of the benefits and pitfalls of basic statistical principles is required. When setting up a trial,

Multivariate or multivariable regression?

The goal is to make a clear distinction between multivariate and multivariable analyses and to identify the nuances that make these types of analyses so distinct from one another.

The Prevention and Treatment of Missing Data in Clinical Trials: An FDA Perspective on the Importance of Dealing With It

The panel recently published a report with recommendations that will be of use not only to the FDA but also to the entire clinical trial community so that the latter can take measures to improve the conduct and analysis of clinical trials.

Reporting and Methods in Clinical Prediction Research: A Systematic Review

It is found that the majority of prediction studies do not follow current methodological recommendations and need to be re-examined.

The ASA Statement on p-Values: Context, Process, and Purpose

Cobb’s concern was a long-worrisome circularity in the sociology of science based on the use of bright lines such as p< 0.05: “We teach it because it’s what we do; we do it because it’s what we
