Trial reportJCO precision oncology2025
Trial report in JCO precision oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01864746 (Phase III Study Evaluating Palbociclib), which is not on this map. Not yet cited in PubMed.
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

Abstract
purposeThe PENELOPE-B trial (ClinicalTrials.gov identifier: NCT01864746) recruited patients with hormone receptor+/human epidermal growth factor receptor 2- early breast cancer without a pathological complete response after taxane-containing neoadjuvant chemotherapy and at a high risk of relapse. Patients were randomly assigned (1:1) to receive 13 cycles of palbociclib once daily or placebo on days 1-21 in a 28-day cycle in addition to endocrine therapy (ET). PENELOPE-B did not show improved invasive disease-free survival (iDFS) after adding palbociclib to ET. This retrospective analysis investigated the impact of germline pathogenic variant (PV) status of
methodsIn total, 445 patients were sampled following a case-cohort design and 442 were analyzed for germline PVs. Statistical analyses were performed for time-to-event end points (iDFS, distant disease-free survival [DDFS], and overall survival [OS]).
resultsOf the 442 patients, 42 carried PVs in any cancer predisposition gene; 15 carried
