Interesting analyses from @healthfoundation.bsky.social this morning on who is accessing private prescriptions for GLP-1 drugs for obesity. Data like this has been hard to come by, yet private access is such an important component for GLP-1 use.

Thrilled to share my latest paper entitled, "Estimating Discrimination in Sentencing: Distinguishing between Good and Bad Controls" Led by @jpinasanchez.bsky.social, the paper introduces a framework for examining discrimination in criminal justice processes. 🧵 1/10 publicera.kb.se/ejels/articl...
Screenshot of title page including the following abstract:

To minimise confounding bias and disentangle warranted from unwarranted disparities, researchers examining sentencing discrimination have traditionally sought to control for as many legal factors as possible. However, over the past decade, a growing number of scholars have questioned this strategy, noting that many legal factors are themselves subject to judicial discretion and that controlling for them can introduce post-treatment bias. Here, we use directed acyclic graphs (DAGs) to provide a formal and comprehensive assessment of the different types of bias that may arise from different choices of controls. In addition, we propose a new modelling framework to facilitate the selection of controls and reflect the model uncertainty created by the trade-off inherent in judicially-defined legal factors and other factors with a similar dual causal role. We apply this framework to examine race disparities in US federal courts and gender disparities in the England and Wales magistrates’ court. We find substantial model uncertainty for gender disparities and for race disparities affecting Hispanic offenders, rendering estimates of the latter inconclusive. Disparities against black offenders are more consistent and — under specific conditions — could be interpreted as evidence of direct discrimination.

Lauren Bandy and I got a short piece in BMJ arguing that the proposed changes to UK sugar drink tax target the wrong end of the market. Changing the threshold where tax is applied from 5g sugar/100mL to 4g only hurts those that have ALREADY reformulated and changes nothing for high sugar drinks.

Dear Birch JM,

 

This is a mild update. On the date we indicated March 10, 2025, we notified you of your article submission. Whether you didn't receive our invitations or we just couldn't get in touch with you, we're still confused.

Please review those emails and get back to us as soon as possible with any information you need for publishing or to send a cover letter and manuscript to this address, even if it happened by accident.

We would appreciate it if you could respond so that we don't have to contact you again.
