Observational study in Future oncology (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04498481 (TREATMENT AND MONITORING PATTERNS AND CLINICAL OUTCOMES IN PATIENTS RECEIVING PALBOCICLIB PLUS AROMATASE INHIBITOR OR PALBOCICLIB PLUS FULVESTRANT AS TREATMENT OF HORMONE RECEPTOR POSITIVE), which is not on this map.

1 · What the graph read from it

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.

2 · The registry

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.

Abstract

aimsTo investigate real-world treatment patterns and outcomes among patients with hormone receptor-positive/human epidermal growth factor 2-negative (HR+/HER2-) metastatic breast cancer (mBC) who initiated first-line palbociclib-fulvestrant. PATIENTS &

methodsRetrospective observational study of iKnowMed electronic health records among patients who initiated first-line palbociclib-fulvestrant between 1 February 2016 and 31 December 2019 and were followed through 30 June 2020. Demographic, clinical, and treatment characteristics were evaluated descriptively. Endpoints including real-world progression-free survival, overall survival, time to chemotherapy, real-world duration of therapy, and time to next treatment were assessed using Kaplan-Meier methods from first-line treatment initiation.

results317 patients were included (median age 67.3 years, 90.5% post-menopausal, 36.9% bone-only disease, 15.9 months median follow-up). Among those with prior adjuvant treatment (

conclusionsThese results suggest favorable real-world clinical outcomes associated with first-line palbociclib-fulvestrant among patients with HR+/HER2- mBC. (clinical trial registration: NCT04498481).
