Decoding NATALEE and MonarchE eligibility criteria in a real-world cohort of early breast cancer patients.
Article in The oncologist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The NATALEE trial expanded the use of adjuvant cyclin-dependent kinase 4/6 inhibitors beyond the MonarchE trial's criteria for early breast cancer (eBC). We conducted a retrospective analysis comparing a large real-world (RW) cohort of 762 consecutive eBC patients with those enrolled in the NATALEE and MonarchE randomized controlled trials (RCTs) to evaluate differences in eligibility. Our analysis revealed that 41.7% of RW patients met NATALEE's eligibility criteria, significantly more than the 21.8% who met MonarchE's criteria, reflecting NATALEE's broader indication. Real-world patients were older, had less advanced tumors, and were less likely to be treated with adjuvant chemotherapy compared to the RCT populations. None of the RW patients was deemed eligible for ribociclib based solely on high genomic risk. These findings underscore significant differences in clinical characteristics and potential treatment eligibility, highlighting the need for critical assessment of RCTs results in clinical practice.
