## Description

Pediatric Limb Length Calculator is a browser-based calculation prototype intended
for use in pediatric orthopedics. It estimates lower-limb length discrepancy and
theoretical epiphysiodesis timing using the multiplier method. The interface supports
English and French.

Authorized users can create and manage their own records. Site administrators can
view all records and manage user access. Records include patient names, measurement
dates, entered measurements and calculation results, and are stored in the WordPress
database.

**Clinical disclaimer:** Pediatric Limb Length Calculator is a calculation prototype,
not a clinically validated medical device. Its calculations, assumptions, multiplier
data and inferred correction described below require independent verification. Do
not use it as the sole basis for diagnosis, treatment planning or epiphysiodesis
decisions. Verify all measurements and results with a qualified specialist.

The site owner is responsible for access control, secure hosting, HTTPS, protected
backups, appropriate retention, and compliance with applicable privacy and health-
data laws. Do not enter real patient data into a test or publicly accessible installation.

### Source code and development

The plugin JavaScript and CSS are provided as readable, non-minified source files:`
pediatric-limb-length-calculator.js` and `pediatric-limb-length-calculator.css`.
These files are maintained in the public project repository: https://github.com/
RedaAmani/OrthoGrowth

No compilation, bundling or minification step is required. Developers can inspect
and modify these files directly. The plugin’s PHP, JavaScript, CSS and template 
files are included in the plugin package under the GPL-compatible license stated
above.

### Privacy and data retention

Pediatric Limb Length Calculator stores patient names, measurement dates, measurements
and calculation results. Authorized non-administrator users can access only records
they created; site administrators can access all records. The plugin registers WordPress
personal-data exporter and eraser callbacks for records associated with a WordPress
account. Erasing an account’s Pediatric Limb Length Calculator data permanently 
deletes records created by that account.

By default, uninstalling the plugin preserves saved records. An administrator can
explicitly enable permanent deletion on uninstall in the Pediatric Limb Length Calculator
administration menu. If enabled, uninstalling deletes records for the relevant site;
with network activation, the setting is evaluated separately for each site. Keep
secure backups and establish a retention policy appropriate to your jurisdiction.

### Sources and attribution

The multiplier-method approach is based on published orthopedic literature, including:

   length discrepancy. _Journal of Bone and Joint Surgery American_. 2000;82(10):
   1432–1446. https://pubmed.ncbi.nlm.nih.gov/11057472/
 * Mills G, Nelson S. An improved spreadsheet for calculating limb length discrepancy
   and epiphysiodesis timing using the multiplier method. _Journal of Children’s
   Orthopaedics_. 2016;10:313–319. https://doi.org/10.1007/s11832-016-0754-4

CC BY 4.0): https://creativecommons.org/licenses/by/4.0/. Article-derived material
must be attributed to the authors and source, linked to the license, and any changes
disclosed. The source table’s value for girls at 3.08 years is printed as 3.03, 
which appears inconsistent with adjacent rows. Pediatric Limb Length Calculator 
uses 2.03 as an inferred correction, not as a value explicitly printed in the article.
This correction must be independently checked before any clinical use.

## Installation

 1. Upload the `pediatric-limb-length-calculator` folder to `/wp-content/plugins/`,
    or install the plugin ZIP through the WordPress Plugins screen.
 2. Activate Pediatric Limb Length Calculator. On multisite installations, network 
    activation creates a separate records table for each site, including newly created
    sites.
 3. Open the Pediatric Limb Length Calculator menu in the WordPress administration 
    sidebar and grant access to individual users.
 4. Create a page available only to authorized users and add the shortcode `[pediatric-
    limb-length-calculator]`.
 5. Test calculation, saving, loading, exporting and deletion with fictitious data 
    before any real use.

## FAQ

### Does Pediatric Limb Length Calculator provide a clinical diagnosis?

No. It provides estimates only. It is not a validated medical device and must not
be used alone to make treatment decisions.

### Who can view saved records?

Authorized users can view their own records. Site administrators can view all records.

### Can I export or erase records associated with a WordPress account?

Yes. The plugin provides callbacks for the WordPress personal-data export and erasure
tools. The eraser permanently deletes Pediatric Limb Length Calculator records created
by the account being processed.

### What happens when the plugin is uninstalled?

Records are preserved by default. Permanent deletion occurs only if an administrator
enabled the corresponding option before uninstalling. On multisite, this setting
is applied per site.
