Superior 125-month outcome through cetuximab in the larynx organ preservation trial DeLOS-II: a single study center's experience.

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
Introduction: The larynx organ preservation (LOP) trial DeLOS-II enrolled Methods: Our cohort of 52 DeLOS-II patients accrued between 2007 and 2012 included 27 and 25 patients randomized to arms A and B, respectively. F was omitted because of severe toxicity with amendment 2 of the DeLOS-II protocol, leading to 21 and 31 patients receiving TPF and TP IC backbone, respectively. Follow-up data were collected using electronic health records and information from the German Centre for Cancer Registry Data to evaluate long-term LFS and OS in treatment groups. Results: According to ETSS ≥ 30%, 42 patients (80.8%; 21 and 21 corresponding to 77.8% and 84.0% in arms A and B, respectively) were responders to IC-1 and underwent the LOP attempt. Recommending early TL to non-responders (ETSS < 30%), eight patients (five and three in A and B, respectively) underwent early TL. At 125 months, 22 (eight and 14) patients were alive: 17 (six and 11) with a functioning larynx and five (two and three) without a larynx. Arm B had superior OS ( Conclusion: While the per-protocol DeLOS-II results earlier reported comparable 24-month LFS and OS in arms A and B, our subcohort's long-term follow-up data demonstrate a superior 125-month outcome in arm B.
