Association Between Cervical Range of Motion and Swallowing Speed in Older Women After Total Hip Arthroplasty: A Cross-Sectional 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 purposeTotal hip arthroplasty (THA) may induce acute alterations in spinopelvic alignment and compel the cervical spine to compensate for postural balance. Although these changes may biomechanically affect swallowing speed, the relationship between cervical range of motion (ROM) and swallowing speed in older adults after THA remains unclear. Therefore, this study aimed to investigate the relationship between cervical ROM and swallowing speed in older women after THA.
methodsThis cross-sectional study included 60 older women (mean age 71.6 ± 5.5 years) without clinically significant self-reported dysphagia (10-item eating assessment tool < 3) undergoing rehabilitation after THA. Swallowing speed was assessed using a 100-mL water swallowing test. Cervical ROM (flexion and extension) was measured using a CROM3 device. Multiple regression analyses were performed adjusting for age, potentially inappropriate medications, and maximum tongue pressure (MTP) to investigate the association between swallowing speed and cervical ROM.
resultsCorrelation analysis showed a weak positive correlation between cervical extension ROM and swallowing speed (r DISCUSSION: Restricted cervical extension ROM was weakly associated with decreased swallowing speed in older women after THA. This association suggests only a modest relationship without direct predictive value for clinical swallowing speed. Therefore, evaluating cervical extension ROM may be considered an adjunctive observation rather than a screening tool for swallowing dysfunction.
