Protocol for a single-arm, multicenter, prospective, confirmatory phase III trial of wedge resection for invasive ground glass opacity-featured lung cancer with a size ≤2 cm and a consolidation tumor ratio between 0.25 and 0.5 (ECTOP-1020 study).
Article in Journal of thoracic disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06102161 (Wedge Resection for Ground-glass Opacity-featured Lung Cancer With Size Less Than 2cm and Consolidation-to-tumor Ratio Between 0.25 to 0.5), 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

Abstract
Background: Segmentectomy is the current standard treatment for ground glass opacity (GGO)-featured lung cancer patients with a tumor size ≤2 cm and a consolidation tumor ratio (CTR) between 0.25 and 0.5. However, compared with wedge resection, segmentectomy destroys the patient's hilar structure and consumes more lung parenchyma. A recent study demonstrated that wedge resection could yield comparable results for this group of patients. Methods: This study aimed to confirm the noninferiority of wedge resection over standard surgery in invasive GGO-featured lung cancer patients with a size ≤2 cm and a CTR between 0.25 and 0.5, as measured by 5-year overall survival (OS). The primary endpoint is 5-year OS. The secondary endpoints are 5-year recurrence-free survival (RFS), the R0 resection rate, pulmonary function, recurrence and metastasis sites, and adverse events after surgery. During the trial period, 286 patients are enrolled from six Chinese institutions. Discussion: The primary results of this study will be actively disseminated through manuscript publications and conference presentations. This prospective study will evaluate the surgical efficacy and safety of wedge resection for small (tumor size ≤2 cm with a CTR between 0.25 and 0.5) invasive GGO-featured lung cancer and will support the standardization of this surgical strategy. Trial Registration: This trial has been registered on ClinicalTrial.gov (No. NCT06102161).
