1 · What the graph read from it

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.

2 · The registry

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

purposeOlder adults undergoing hemodialysis experience improved survival rates but often suffer from sleep disorders, resulting in adverse health outcomes. This study aims to assess the association between handgrip strength (HGS), a key indicator of muscular strength, and sleep quality in older adults undergoing hemodialysis.

methodsThis cross-sectional and analytical study assessed 150 older adults undergoing hemodialysis selected by simple randomization. Data on demographics, clinical parameters, HGS, and sleep quality (PSQI) were collected and analyzed using descriptive and inferential statistics with SPSS version 20.

resultsThe mean age of the participants was 65.61 ± 4.07 years. Mean mid-upper arm circumference (MUAC) and calf circumference (CC) were 29.59 cm and 36.96 cm, respectively. The mean HGS was 28.7 ± 8.55 kg, with males exhibiting higher HGS (37.72 ± 6.17 kg) than females (23.55 ± 5.38 kg). The mean PSQI score was 6.71, with 54.1% reporting poor sleep quality. Sleep quality was significantly associated with income source, underlying diseases, Charlson Comorbidity Index (CCI), BMI, MUAC, CC, HGS, and blood levels of potassium and creatinine. A moderate negative correlation (r = - 0.438, p < 0.001) was observed between HGS and PSQI scores, indicating better sleep quality with greater muscular strength. Elevated potassium levels increase the risk of poor sleep.

conclusionsOlder adults undergoing hemodialysis frequently experience poor sleep quality, which is associated with lower muscular strength. These findings highlight the importance of implementing targeted interventions, such as strength-training programs, to improve muscular strength and, consequently, sleep quality in this vulnerable population.
