Prognosis of Invasive Lobular Carcinoma and Effectiveness of Eribulin in Clinical Practice: A Post Hoc Analysis of a 2-Year Post-Marketing Surveillance.
Observational study in Asia-Pacific journal of clinical 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 NCT02371174 (An Observational Post-Marketing Surveillance Study on the Status and Factors for the Development of Peripheral Neuropathy in Patients With HER2-Negative Inoperable or Recurrent Breast Cancer in Japan.), which is not on this map.

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.

Abstract
aimInvasive lobular carcinoma (ILC) is the second most common breast cancer type after invasive ductal carcinoma (IDC). Eribulin mesylate (eribulin) is a non-taxane microtubule dynamics inhibitor approved for advanced or metastatic breast cancer, including ILC and IDC. However, real-world data from eribulin-treated patients with advanced or metastatic ILC are scarce.
methodsThis post hoc analysis of a Japanese multicenter, prospective, observational post-marketing surveillance (ClinicalTrials.gov: NCT02371174) evaluated data from eribulin-treated patients with ILC or IDC. Overall survival (OS) from the initiation of first-line chemotherapy, OS from the first date of eribulin administration, and time-to-treatment failure (TTF) were evaluated. OS from eribulin initiation was also evaluated by line of eribulin treatment (first-line, second-line, and third-line or later). Adverse drug reactions (ADRs) with ≥ 5% frequency in both groups were evaluated.
resultsAmong patients with ILC (n = 33) and IDC (n = 543), median OS from the initiation of first-line chemotherapy was 25.5 and 39.0 months, respectively (hazard ratio 1.94 [95% confidence interval 1.28-2.94]; p < 0.05), median OS from the first date of eribulin administration was 16.0 and 18.0 months, respectively (1.31 [0.87-1.97]), and TTF was 6 and 5 months (0.92 [0.65-1.32]). No significant differences were observed in median OS when stratified by line of eribulin treatment. Type and frequency of ADRs did not differ significantly between the groups.
conclusionOS and TTF after eribulin initiation were similar between ILC and IDC cases, suggesting that eribulin might be a beneficial treatment option for ILC.
