Estimating Long-Term Survivorship Rates Among Patients With Resected Stage III/IV Melanoma: Analyses From CheckMate 238 and European Organization for Research and Treatment of Cancer 18071 Trials.
Trial report in Journal of clinical oncology : official journal of the American Society 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 2 registered trials, which are 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
purposeStandard-of-care treatments for patients with resected stage III/IV melanoma include the immuno-oncology (IO) agents nivolumab (NIVO) and ipilimumab (IPI). This study used mixture cure models (MCMs) to estimate cure rates among patients treated with NIVO or IPI in the phase III CheckMate 238 (ClinicalTrials.gov identifier: NCT02388906) and European Organization for Research and Treatment of Cancer (EORTC) 18071 (ClinicalTrials.gov identifier: NCT00636168) trials, and to assess the impact of use of adjuvant immunotherapy on cure rates versus watchful waiting.
methodsMCMs were applied to patient-level recurrence-free survival data from CheckMate 238 and EORTC 18071. Cured patients were assumed to experience no disease recurrence and mortality risks similar to the general population. Uncured patients were at risk of disease recurrence and all-cause death. The survival trend of the cured patients was estimated using life expectancy data for a general population with the same baseline demographic characteristics. A regression model assessed the odds ratios (ORs) of cure across key subgroups on the basis of baseline characteristics of the study populations.
resultsIn CheckMate 238, estimated cure rates were 48.3% (95% CI, 41.8 to 54.9) with NIVO and 38.2% (95% CI, 32.7 to 44.1) with IPI. In EORTC 18071, estimated cure rates were 38.0% (95% CI, 32.1 to 44.2) with IPI and 29.2% (95% CI, 24.4 to 34.6) with placebo. In the indirect comparison of the two trials, the odds of cure were significantly higher with NIVO than with placebo (OR, 2.33 [95% CI, 1.49 to 3.65]).
conclusionAnalyses involving two large phase III trials investigating adjuvant IO treatment for resected melanoma demonstrate higher cure rates for both NIVO and IPI than placebo, with NIVO providing the highest cure rate. Similar cure rates were estimated for patients treated with IPI in both trials, despite staging and dosing differences.
