Association Between Kyphosis and Sleep Disturbance in Community-Dwelling Older Adults: The Locomotive Syndrome and Health Outcome in Aizu Cohort 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
purposeWorsening sagittal alignment of the spine, particularly kyphosis, may cause difficulty in assuming a supine position, restricting sleeping posture and movement and potentially leading to sleep disturbances. However, no studies have explored the relationship between sagittal spinal alignment and sleep disturbance. This study aimed to clarify the relationship between sagittal spinal alignment and sleep disturbance.
methodsData were drawn from the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS) in 2010. Sleep disturbance was assessed using a self-administered questionnaire on average sleep duration over the past month, with patients classified as having sleep disturbance if they slept for fewer than six hours per day. The sagittal vertical axis (SVA) was measured on standing whole-spine radiographs and classified into three groups based on the Scoliosis Research Society Schwab classification: non-kyphosis: <40 mm; moderate kyphosis: 40-95 mm; and severe kyphosis: >95 mm. Age, sex, drinking habits, depressive symptoms, overactive bladder symptoms, and napping habits were assessed as confounding factors. The association between SVA and sleep disturbance was evaluated using adjusted odds ratios and 95% confidence intervals (CIs).
resultsThe percentage of sleep disturbance among the 772 subjects in the analysis was 8.9% for non-kyphosis, 9.1% for moderate kyphosis, and 20.0% for severe kyphosis. Using non-kyphosis as the reference, adjusted odds ratios (ORs; 95% confidence intervals (95% CIs)) were 1.16 (0.65-2.05) for moderate kyphosis and 2.86 (1.13-7.26) for severe kyphosis.
conclusionKyphosis in community-dwelling adults was found to be associated with sleep disturbance. Therefore, it is necessary to focus on the parasomnias of sleep disturbance in patients presenting with spinal kyphosis.
