CT texture features of lung adenocarcinoma with HER2 mutation.
Article in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundMutations in human receptor tyrosine kinase epidermal growth factor receptor-2 (HER2) are rare. This study aimed to investigate the clinical characteristics and computed tomography (CT) texture features of lung adenocarcinoma (LUAD) patients with HER2 mutation.
methodsThis study included 933 LUAD patients from January 2018 to December 2023 and classified their CT textures accordingly.
resultsThe data indicated that the incidence of HER2 mutation was higher in younger LUAD patients than in elder patients [7.5% (31/413) vs. 1.5% (8/520), p < 0.0001] and was associated with never-smokers [0% (0/78) vs. 4.6% (39/855), p = 0.03]. In this study, the tumors were categorized based on their diameter into T1a and ≥ T1b. The data revealed that HER2 mutation was more frequent in T1a than in ≥ T1b [11.0% (23/210) vs. 2.2% (16/723), p < 0.0001]. Furthermore, non-pSD was more common than pSD in LUAD with HER2 mutation than in LUAD with HER2 wild type [82.1% (31/39) vs.17.9% (7/39), p = 0.01]. Moreover, the size of pGGO (0.94 ± 0.29 cm vs. 1.24 ± 0.39 cm, p = 0.0009), mGGO (0.86 ± 0.39 cm vs. 1.5 ± 0.77 cm, p < 0.0001) and pSD (1.75 ± 0.81 cm vs. 2.5 ± 1.4 cm, p < 0.05) in LUAD patients with HER2 mutation was smaller than those with HER2 wild type patients. In addition, when LUADs with HER2 wild type transformed from pGGO to mGGO, their sizes increased significantly (1.50 ± 0.77 cm vs. 1.24 ± 0.39 cm). It was also observed that the incidence of LUAD with HER2 mutation of ≤ 1 cm was significantly more than that of > 1 cm comparing to that in LUAD with HER2 wild type [14.8% (12/81) vs. 1.7% (3/173), p < 0.0001].
conclusionThis study indicated that the incidence of HER2 mutation was higher in younger and never-smoking LUAD patients. Furthermore, the growth of LUAD with HER2 mutation was slower than that of those with HER2 wild type. Moreover, most LUAD with HER2 mutation changed into pSD after > 1 cm.
