## Overview

This Flask application serves a stroke-risk form, converts submitted demographic and health fields into model inputs, combines a trained-model prediction with threshold-based risk rules, and displays a result. Its other visible user-facing branches include a BMI calculator and counseling page. The README describes model training and evaluation, and the tree contains a dataset and training script; the sampled training code is commented out, so that branch is shown as inactive. The CTA route references a template absent from the tree. Evidence is limited to the README, tree, and sampled files.

Main entry points: [`app.py`](https://github.com/anand-nayak-git/stroke-prediction-system/blob/main/app.py) (Flask routes), [`strokenew.pkl`](https://github.com/anand-nayak-git/stroke-prediction-system/blob/main/strokenew.pkl) (Trained model), [`templates/predict.html`](https://github.com/anand-nayak-git/stroke-prediction-system/blob/main/templates/predict.html) (Prediction form), [`templates/bmi.html`](https://github.com/anand-nayak-git/stroke-prediction-system/blob/main/templates/bmi.html) (BMI page)
