Relationship between trajectory of sleep quality and short-term changes in residual renal function in stage 3-5 chronic kidney disease patients.

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
backgroundChronic kidney disease (CKD) is commonly associated with sleep disturbance. However, the relationship between the trajectory of sleep quality and short-term residual renal function is not clear. Thus, this study aimed to investigate such relationship.
methodsIn total, 132 patients with CKD stage 3-5 were prospectively enrolled. All participants were followed-up for 6 months. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used to assess sleep quality. The longitudinal PSQI and estimated glomerular filtration rate (eGFR) were measured at baseline, the 3rd month and 6th month. The participants were stratified into three groups according to the PSQI trajectories. The primary outcome was set as the eGFR change among 6 months less than the median.
resultsSixty nine participants showed PSQI ≤ 5 at baseline and 15 patients had increased scores > 5 at 3rd month among them. 63 participants showed PSQI > 5 at baseline and 11 patients had decreased scores ≤ 5 at 3rd month. Only in patients whose baseline PSQI ≤ 5 but increased to > 5 at 3rd month presented a longitudinal decline in eGFR at both 3rd month and 6th month compared with baseline eGFR. Linear regression analysis for eGFR change showed no significant association between eGFR change and PSQI score. Logistic regression revealed worsen sleep quality will deteriorate renal function.
conclusionA relationship was observed between worsening sleep quality and eGFR decline in non-dialysis CKD patients.
