Those subgroups are tested on independent data to assess their consistency across databases, while preserving statistical power by limiting the number of tests. The top-k credible subgroups are then selected, while accounting for subgroups’ diversity and, possibly, clinical relevance. This allows Q-Finder to directly target and assess subgroups on recommended credibility criteria. It combines an exhaustive search with a cascade of filters based on metrics assessing key credibility criteria, including relative risk reduction assessment, adjustment on confounding factors, individual feature’s contribution to the subgroup’s effect, interaction tests for assessing between-subgroup treatment effect interactions and tests adjustment (multiple testing).
#QFINDER SHOWING UP TWICE DRIVERS#
In this paper, we present the Q-Finder algorithm that aims to generate statistically credible subgroups to answer clinical questions, such as finding drivers of natural disease progression or treatment response. However, both the limited consideration by standard SD algorithms of recommended criteria to define credible subgroups and the lack of statistical power of the findings after correcting for multiple testing hinder the generation of hypothesis and their acceptance by healthcare authorities and practitioners. Within the latter area, subgroup discovery (SD) data mining approach is widely used-particularly in precision medicine-to evaluate treatment effect across different groups of patients from various data sources (be it from clinical trials or real-world data).

In randomized clinical trials (RCTs), confirmatory subgroup analyses focus on the assessment of drugs in predefined subgroups, while exploratory ones allow a posteriori the identification of subsets of patients who respond differently.

They unapologetically embrace and celebrate their femininity, also leaning into their sexuality for the first time with these displays.


With dedicated time slots for solo performances, each member gets their time to connect with audiences in a more personal way by performing covers or singing solo material. 2 on the Billboard 200 –“Ready to Be.” A few key elements stand out in their newness: On this year, for the first time, a drummer and guitarist join the girls on stage about mid-way into the set, adding a tinge of freshness to older singles like “What is Love” and “Queen of Hearts.” And though Twice is known for singing sugary pop songs about love, they certainly deliver one of the edgiest K-pop shows the U.S. This time the girl group visits North America in support of their 2023 EP - and their first No.
