Body roundness index

What do you think of the BRI vs. BMI? Also, this.

We don't have an article on BRI yet, but it's getting more public attention. Might be worthwhile to include in your calculators project. Zefr (talk) 01:28, 21 September 2024 (UTC)[reply]

User:Zefr Yah for sure it would be reasonable to have that calculator aswell. Do you want to give it a try building it? It is not that complicated. Doc James (talk · contribs · email) 02:07, 21 September 2024 (UTC)[reply]

Sure. Will work at it over the next few days, and will alert you here. Zefr (talk) 02:18, 21 September 2024 (UTC)[reply]

A start class article is completed. Would benefit from your review and edits. Zefr (talk) 02:29, 24 September 2024 (UTC)[reply]

Amazing. You want to build a calculator to go in the article? Doc James (talk · contribs · email) 02:09, 25 September 2024 (UTC)[reply]

Using this format, I drafted an equation and tried to solve my own BRI, but it looked and felt clumsy.

When you say "build", how does that work? It would be a significant public contribution for Wikipedia to provide a calculator. The one in the article is easy to use, but is owned by a commercial enterprise. The one offered in the Thomas article is defunct.

For the article, I copied and cited the equation from the 'BRI definition' in the Zhang article, but the original equation development is more extensive and calculus-based under 'Supplementary material' (downloadable file) in the Thomas article. Zefr (talk) 02:42, 25 September 2024 (UTC)[reply]

User:Zefr Okay here is a draft User:Doc James/BRI. Will need some work to get it to function with metric and imperial like we have for BMI. Also need to figure out how to get two significant figures after the decimal point. Doc James (talk · contribs · email) 03:24, 25 September 2024 (UTC)[reply]

The variables presented in the calculation in your draft and in the article (from the Zhang source) are waist circumference and height, but the original Thomas calculation (from the publication under Web-based Calculator states: Screen shot of Body Roundness Calculator. After the user enters personal information for age, height, weight, sex, race, waist and hip circumferences, the program outputs total percent body fat, amount and percent of VAT, the body roundness index, and whether the individual is within the determined healthy range of body roundness. A graph depicting the resulting individual ellipse (African American curve) and healthy range (green shaded area) provide the user a visual representation of their body roundness relative to the healthy range. (my underlining).

In the Discussion, Thomas summarizes: "we may have reached the limits of maximal accuracy of predictions of VAT and % body fat that rely solely on the circumference measurements (waist and hip), age, height, sex, race, and weight."

The easy-to-use calculator here uses these same 6 variables (race/ethnicity is optional).

I explained in the article under Calculation: "The only device needed to determine BRI is a measuring tape for circumference of waist and hips, and determination of height," which comes from the sources.

Thoughts on best dealing with these variations for the BRI calculator? Zefr (talk) 18:47, 25 September 2024 (UTC)[reply]

That calculator provide Percent Body Fat, BMI, and BRI. Depending which one of those you want you need to provide different variable. For BRI you only need height and waist. And that is all my BRI calculator uses. Doc James (talk · contribs · email) 18:56, 25 September 2024 (UTC)[reply]

Anyway the calculator can also be adjusted to take imperial as we see here mdwiki:Template:BMI calculator2 Doc James (talk · contribs · email) 00:25, 26 September 2024 (UTC)[reply]

User:Zefr Built another one here mdwiki:Pulmonary_embolism#Probability_testing Doc James (talk · contribs · email) 00:57, 26 September 2024 (UTC)[reply]

Both the BMI and PE calculators are nice. What is needed to finish the BRI calculator? Zefr (talk) 01:07, 26 September 2024 (UTC)[reply]

Would be nice if it accepted metric or imperial, similar to the BMI calculator. Doc James (talk · contribs · email) 01:18, 26 September 2024 (UTC)[reply]

Another one at mdwiki:Chest_pain#Risk_scores. Same data that EN WP provides but is interactive and calculates a result based on user imputs. Doc James (talk · contribs · email) 02:04, 26 September 2024 (UTC)[reply]

Another good one. Given your experience in building the BMI calculator, can't that one be the model to complete the BRI? I wasn't following the VP-Tech discussion you had earlier this month - are there editors from there that could finish the BRI?

As I didn't have VP-Tech on my watchlist, and didn't know about your discussion, I posted a question there today. Apologies for the replication. Zefr (talk) 02:42, 26 September 2024 (UTC)[reply]

User:Zefr tool takes a bit of trial and error. Have the inputs formating correctly for metric and imperial here User:Doc James/BRI2 but just struggling to get the formula to work... Doc James (talk · contribs · email) 03:22, 26 September 2024 (UTC)[reply]

User:Zefr okay have it working now. Will need to get the tool activated by default to have it be generally useful. That will require consensus at WT:MED and VPT. Doc James (talk · contribs · email) 15:16, 26 September 2024 (UTC)[reply]
