Panitumumab plus 5-fluorouracil and folinic acid or 5-fluorouracil and folinic acid alone as maintenance therapy in RAS wild-type metastatic colorectal cancer (PanaMa, AIO KRK 0212): final efficacy analysis of a randomised, open-label, phase 2 trial.
Article in EClinicalMedicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01991873 (Randomized Phase II Study for Evaluation of Efficacy and Safety of Maintenance Treatment With 5-FU/FA Plus Panitumumab vs. 5-FU/FA Alone After Prior Induction Treatment With mFOLFOX6 Plus Panitumumab and Re-induction With mFOLFOX6 Plus Panitumumab in Case of Progression for First-line Treatment of Patients With 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.

Abstract
Background: The PanaMa trial aimed to compare the efficacy of 5-fluorouracil and folinic acid (FU/FA) ± panitumumab maintenance in untreated Methods: In this final phase 2 trial analysis, adult mCRC patients responding to six cycles of FU/FA, oxaliplatin and panitumumab were randomized (1:1, open-label) to maintenance of either FU/FA + panitumumab or FU/FA alone. The primary endpoint was superiority of progression-free survival of maintenance (PFS; time from random assignment to progression/death) in favour of FU/FA + panitumumab. Secondary endpoints included PFS of re-induction (PFS re-ind.), time to failure of strategy (TFS) and overall survival (OS). The trial is registered with ClinicalTrials.gov (NCT01991873). Findings: In 248 patients of the Full Analysis Set recruited between May 2014 and February 2021, with a median observation of 64.0 (range 12.5-86.3) months and 59.7 (range 3.7-97.3) months in the treatment arms, 230 events for PFS (92.7%) and 196 events for OS (79.0%) were recorded. Adding panitumumab to FU/FA resulted in significantly longer PFS (8.8 versus 5.8 months, HR = 0.73 (95% CI 0.56-0.94), Interpretation: Panitumumab plus FU/FA might be considered a standard of care maintenance regimen since a potential re-induction therapy with panitumumab cannot be guaranteed at the time of maintenance treatment decision.
