1 · What the graph read from it

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

backgroundNearly 90% locoregionally advanced nasopharyngeal carcinoma (LANPC) responds to induction chemotherapy (IC) with significant tumor volume shrinkage. Radiotherapy always follows IC, and reduced volume has been proposed. However, the efficacy and safety of reduced-volume radiotherapy is uncertain.

methodsIn this multi-center, noninferiority, randomized, controlled trial, patients with LANPC who completed IC were randomly assigned (1:1) to receive reduced-volume radiotherapy based on post-IC tumor volume (Post-IC group) or conventional volume radiotherapy based on pre-IC tumor volume (Pre-IC group). The primary endpoint was locoregional relapse-free survival, with a noninferiority margin of 8%. Secondary endpoints comprised adverse events, and quality of life (QoL).

resultsBetween August 7, 2020, and May 27, 2022, 445 patients were randomly assigned to Post-IC (n = 225) or Pre-IC (n = 220) groups. The average volume receiving radical dose was 66.6 cm

conclusionsIn this trial, reduced-volume radiotherapy was noninferior to conventional volume radiotherapy in locoregional relapse-free survival, and was associated with lower toxicities and improved QoL. (ClinicalTrials.gov identifier NCT04384627).
