Conformal prediction to adequately cover a specific share of out-of-sample observations.

Key advantage: well-calibrated intervals regardless of the prediction model we use (even a misspecified one).

Spoiler alert: 95% CIs don’t cover 95% of unseen observations! 🫢

Making patient experiences more clinically relevant via LLMs

I used 🦙 3.2 in R for sentiment analysis on ICU’s Drug Reviews dataset for free-text classification, and perceived side effect extraction

Revealing patterns combining objective and subjective insights can emerge!

Confounding in observational data? Meet the parametric g-computation.

Steps:
1. Fit a regression for outcomes
2. Create counterfactual datasets (treated vs. untreated, Fig1)
3. Predict outcomes, compare means = treatment effect (Fig2)

Implementation in R using {marginaleffects}

Our researcher @JRMunell led a study quantifying the tracking of Moderate-Vigorous Physical Activity (MVPA) across childhood and adolescence in a recent cohort from England.
Results? Moderate tracking... but we could do more about it!

📊 Our latest meta-analysis, incorporating data from over 12,000 participants across 7 countries, provides new insights into how changes in daily movement behaviors influence obesity risks across the lifespan.

A powerful way to beautify your RMarkdown reports: embedding simple, visual Shiny R Apps.

Example: Obesity Predictor Simulator.
After model fitting (C5.0 algorithm), we predicted probabilities for BMI status.

Video: probabilities flip from no food between meals to sometimes 🤔

It is all about this, people.

Wonderful weekend in the GenAI Health Hackaton organised by the @hospitalclinic

We generated an AI-based, ready-to-use information system for clinicians from free-text data, potentially saving time, money, and resources, optimising treatments.

EPAFit was present during the 10th International Society for Physical Activity and Health Congress in Paris through our colleagues @jdelpozocruz, @BorjadelPozoCr1, and @jaimeloga98.

Well done team!

Importance of individual-level treatment estimates when great inter-personal variability exists for regulatory decision-makers.

In addition, how do you think is more appropriate: treat the time as discrete or continuous variable to visualise changes over time? 🤔

[Daniel Gallardo-Gómez @DanielG12754470]

Minimally (clinically) important difference and minimal effective dose.

If we have evidence of the minimal impact that must have a treatment, we can predict the exact dose required to reach this goal, and potentially, save money.

Prednisone presented fewer adverse events in people with Crohn’s Disease (CD) than other treatments.

Males had more associated adverse events than females; and age and BMI were determined as risk factors.

Posterior predictive check showed good performance using poisson family.

[Daniel Gallardo-Gómez @DanielG12754470]

I love spaghettis, but I like spaghettis plots better to visualise the variability in the effect estimate of the conditional expectation with posterior draws across a continuous covariate in our GAM

Souped up!

From EPAFit, we are aware of the importance of data literacy in our society.

It is critical to understand how data is collected, analysed, and interpreted.

Do you want to know more about Bayesian statistics advantages?

Advantages of Bayesian meta-analysis vs. Frequentists

1. We can model the parameters we want to estimate probabilistically.

2. These methods create an actual sampling distribution for parameters of interest, allowing calculate exact probabilities via an ECDF.

Last EPAFit recap of the 2023/24 academic year.

This research group was created on the promises of transparency, robustness, and impactful research on physical activity and public health across lifespan, and we'll keep pushing them.

Courses, projects, articles,... stay tuned!
