Prediction models that reviewers can use.

Risk prediction models developed and validated on your data or on the large databases we work with, from regularised regression to gradient boosting and neural networks, reported to TRIPOD+AI and delivered as a working web calculator.

What it is

A model that predicts, and proves it.

A clinical prediction model estimates an individual's risk of an outcome, death, readmission, complication, response, from things known at the point of decision. Machine learning extends the classical logistic or Cox model with algorithms that can capture non-linear patterns and interactions: penalised (LASSO, ridge, elastic-net) regression, random forests, gradient boosting (XGBoost, LightGBM), and neural networks.

What it is built for

Data, your registry or cohort, or NIS, TriNetX, SEER, UK Biobank, and similar sources.

Methods, regularised regression, random forest, gradient boosting, neural networks; tuning, internal/external validation, calibration, decision curve analysis, SHAP.

Deliverables. TRIPOD / TRIPOD+AI manuscript, reproducible code, and a working web calculator.

The project, step by step

How a prediction-model study runs with Cohira.

Start a prediction model →

1

Scope the model

We agree the outcome, the setting, the predictors available at decision time, and whether your data or a large database is the right source.

2

Protocol & sample size

We pre-specify the pipeline and check the data can support the number of predictors without overfitting.

3

Develop

We train and tune candidate algorithms in reproducible Python or R code, with a transparent baseline model for comparison.

4

Validate & explain

Internal and external validation, calibration, decision curve analysis, and SHAP interpretation.

5

Manuscript & calculator

We draft the TRIPOD+AI paper with you and build the web calculator that accompanies it.

6

Submit & revise

We shortlist the right journals, package the submission, and answer reviewers with you to a decision.
