Observational, prospective, phase 4 study in patients with first-line recurrent and/or metastatic squamous cell carcinoma of the head and neck treated with cetuximab and platinum-based therapy: DIRECT.
Trial report in Cancer reports (Hoboken, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCetuximab plus platinum-based therapy (PBT) followed by cetuximab maintenance until progression (EXTREME) is a guideline-recommended first-line treatment option in recurrent/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). DIRECT (Dose Intensity RElative to CeTuximab) was the first phase 4 observational study evaluating EXTREME administration in the real-world setting.
aimsThe primary aim of this study was to assess the relative dose intensity of cetuximab in patients with R/M SCCHN treated with first-line cetuximab according to the EXTREME regimen. METHODS AND
resultsPatients were ≥18 years old and eligible to receive cetuximab/PBT. Primary endpoint was cetuximab relative dose intensity (RDI). Of prospectively enrolled patients (n = 157), 119 received ≥1 cycle of EXTREME. Practices differing from the EXTREME trial were 5-fluorouracil omission (14%), maintenance cetuximab given every other week (54%), prior cetuximab, disease-free interval <6 months. 64% of patients reached cetuximab RDI ≥80%; mean cetuximab RDI was 88%. 46% of patients received maintenance cetuximab (mean RDI, 91%). Median progression-free survival and overall survival were 4.5 and 9.4 months. No new/unexpected safety findings were observed.
conclusionsThe DIRECT study showed that first-line cetuximab plus PBT was a feasible, beneficial first-line treatment regimen in patients with R/M SCCHN in the real-world setting.
