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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

background and purposeAbemaciclib in addition to adjuvant endocrine therapy for hormone receptor positive (HR+) breast cancer improves disease free survival (IDFS) and overall survival (OS). However, treatment-related adverse events may lead to early discontinuation. Sahlgrenska University Hospital implemented a gradual increase in initial dosing, with the intention to improve tolerability and adherence. Patient/material and methods: This retrospective observational study described adherence, tolerability and healthcare utilization associated with a gradual dose increase of adjuvant abemaciclib. A total of 69 patients aged 31-81 years were treated at Sahlgrenska University Hospital between 1st of April 2023 and 1st of April 2025 with cut-off September 5th, 2025. Clinical encounters and treatment outcomes were extracted from medical records and analyzed using descriptive statistics.

resultsPatients were older and had worse Eastern Cooperative Oncology Group status compared with the monarchE registrational trial. At 12 and 26 weeks, 34 patients (49%) and 25 patients (36%) remained on the full dose of abemaciclib, respectively. Overall, 65 patients (94.2%) and 58 patients (84%) remained on treatment at any dose at 12 and 26 weeks. Treatment discontinuation was mainly driven by low grade adverse events (grade 1-2). During the study period 1069 clinical encounters were recorded; 15 patients (22%) had at least one emergency care encounter and seven (10%) required hospital admission.

interpretationThe gradual dose increase strategy resulted in fewer patients maintaining the full dose at 12 weeks compared with monarchE and TRADE trials, while overall treatment persistence remained high. Treatment discontinuation was primarily driven by cumulative low-grade toxicity and healthcare utilization was considerable.
