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
backgroundAdaptive treatment planning can be made in radiotherapy of head and neck cancer patients for reasons such as changes in tumor volume or weight loss. This study aims to find the role of treatment planning images in monitoring radiotherapy-induced malnutrition and predicting the malnutrition-induced prognosis in head and neck cancer patients.
methodsFor this study, we analyzed 30 patients who received radiotherapy in our clinic between September 2018 and September 2021. Those patients, both regular and completed weekly dietitian counseling notes during radiotherapy and available adaptive radiotherapy planning images, were included in the analysis. All patients had weekly nutritional interventions, including nutritional and anthropometric changes in weight, height, body mass index (BMI), and lean body mass (LBM). Skeletal muscle volume, called cervical muscle gauge (CMG), was measured from the simulation images of beginning and adaptive radiotherapy. Inflammatory parameters, including the neutrophil-lymphocyte ratio (NLR), the platelet-lymphocyte ratio (PLR), and the systemic inflammatory index (SII), were also calculated from weekly total blood counts. For the analysis, anthropometric measurements were compared at the beginning and adaptive treatment time. Progression-free (PFS) and overall (OS) survival were calculated according to weight and CMG changes.
resultsThe median weight loss percentage was 4.8% (0 to 24%). The mean percentage of weight changes, LBM, and CMG were 6.33%, 3.47%, and 9.28%, respectively. Results indicated that BMI (p = 006), weight (p < 0.001), LBM (p < 0.001), and CMG (p = 0.057) decreased during radiotherapy. Hemoglobin levels decreased (p = 0.005), and inflammatory markers increased. There were significant correlations between weight and LBM (p < 0.0001) and CMG (p = 0.005) loss. The median follow-up was 26 months. Loss of weight (PFS; 65.5% vs. 35.7%, p = 0.09, OS; 73.7% vs. 32.1%, p = 0.09), LBM (PFS; 75% vs. 41.1%, p = 0.118, OS; 65.6% vs. 52%, p = 0.221) and CMG (PFS; 56.3% vs. 47.1%, p = 0.516, OS;76.9% vs. 32.4%, p = 0.059) negatively affected three-year survival.
conclusionsCervical muscle volume measurement may help predict malnutrition in patients receiving radiotherapy for head and neck cancer. Our study shows adaptive planning images may be used for this approach. In addition, this method may help to predict prognosis due to malnutrition in patients undergoing radiotherapy.
