Neck muscle training improving the setup of reproducibility in patient with head and neck cancer receiving radiotherapy - a prospective randomized controlled study.

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
background and purposeThe aim of this study is to evaluate the effectiveness of a cervical muscle training intervention in decreasing setup errors in patients head and neck cancer (HNC) undergoing radiotherapy (RT). MATERIALS AND
methodsHNC patients opting for RT at our center. The patients were randomly allocated to either the muscle training group or the control group in a 1:1 ratio. The magnitude of the setup error was measured at the levels of the clivus, C4 and C7 vertebrae respectively. The Van Herk formula was used to determine appropriate planning target volume (PTV) margins. (Trial Registration: ChiCTR2000041009, registration date: 12/16/2020)
resultsA total of 221 patients were analyzed, with 109 assigned to the muscle training group and 112 enrolled in the control group. Compared with the control group, the setup errors in the X and Z direction of the clivus and the Z direction of C4 and C7 in the muscle training group were significantly lower (p = 0.031, < 0.001, < 0.001, < 0.001 respectively). The required PTV margins in the Z direction increased from 2.13 mm in the clivus to 3.63 mm in C7 in the muscle training group and from 2.89 mm in the clivus to 4.37 mm in C7 in the control group. Multivariate linear regression analysis demonstrated that the impact of neck muscle training, weight fluctuation, and cervical curvature on the setup error in the Z direction at C7 differed significantly (p = 0.000, 0.001, and 0.008, respectively).
conclusionNeck muscle training can reduce setup errors and PTV margins in the anterior-posterior direction in patients undergoing RT for HNC.
