First-line treatment of anti-EGFR monoclonal antibody cetuximab β plus FOLFIRI versus FOLFIRI alone in Chinese patients with RAS/BRAF wild-type metastatic colorectal cancer: a randomized, phase 3 trial.
Trial report in Signal transduction and targeted therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03206151 (Open, Randomized, Controlled, Multicenter Phase III Study Comparing CMAB009 Plus FOLFIRI Versus FOLFIRI Alone as First-line Treatment for Epidermal Growth Factor Receptor-expressing, RAS/BRAF Wild-type, Metastatic Colorectal Cancer), 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
Cetuximab plus irinotecan, fluorouracil, and leucovorin (FOLFIRI) represents a first-line therapeutic standard for RAS/BRAF wild-type metastatic colorectal cancer (mCRC) patients. Despite this established approach, cetuximab β (CMAB009), as a modified antibody of cetuximab, prospectively selected for dual RAS/BRAF wild-type patients, has not yet been validated in the Chinese mCRC patients through phase 3 trial. In this study (ClinicalTrials.gov identifier: NCT03206151), patients with RAS/BRAF wild-type mCRC who were not suitable for radical resection were randomly assigned in a 1:1 ratio to receive cetuximab β plus FOLFIRI or FOLFIRI alone. The primary endpoint was blinded independent review committee-assessed progression-free survival (PFS). The secondary endpoints included overall survival (OS), objective response rate (ORR), disease control rate (DCR), surgery rate for metastasis and R0 resection rate, and safety. From January 4, 2018 to September 2, 2021, a total of 505 eligible patients were enrolled and received study treatment; the median follow-up duration was 8.7 months (95% confidence interval [CI], 7.77 to 9.29) and 5.9 months (95% CI, 5.63 to 6.65) in cetuximab β plus FOLFIRI group and FOLFIRI group, respectively. Compared to FOLFIRI alone, cetuximab β plus FOLFIRI demonstrated statistically significant improvements in median PFS (13.1 vs. 9.6 months, hazard ratio [HR], 0.639; 95% CI, 0.468 to 0.872; P = 0.004), median OS (28.3 vs. 23.1 months, HR, 0.729; 95% CI, 0.551 to 0.965; P = 0.024), and ORR (69.1% vs. 42.3%, odds ratio, 3.090; 95% CI, 2.280 to 4.189; P < 0.001). Cetuximab β plus FOLFIRI exhibited manageable toxicity without novel safety signals. This study demonstrated that cetuximab β plus FOLFIRI provided significant clinical benefits as a first-line treatment for patients with RAS/BRAF wild-type mCRC. Compared to FOLFIRI alone, cetuximab β plus FOLFIRI therapy led to prolonged median PFS and OS while maintaining a manageable safety profile, offering a new treatment option for this patient population.
