Impact of chronic kidney disease on adults and their caregivers in the United States: a systematic literature review.
Synthesis in BMC nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe objective of this study was to synthesize estimates of the economic and humanistic burden among adults with chronic kidney disease (CKD) and the economic, humanistic, and clinical impacts among their informal caregivers, in the United States (US).
methodsA systematic literature review was conducted using MEDLINE and Embase, to identify studies reporting estimates of (1) economic or humanistic burden among adults with CKD and (2) economic, humanistic, or clinical impacts on their informal caregivers, published between 2016 and 2025. Two reviewers independently performed study selection and data extraction according to PRISMA guidelines. Study population characteristics were summarized, as were estimates of burden; costs were converted to 2025 USD.
resultsAdults with CKD: From 10,191 citations, 55 studies were included. Mean age ranged from 46 to 81 years; 30–73% were female. Out-of-pocket (OOP) expenditures were estimated at $1,619, $2,189 (mean), and $1,913 (median) annually (3 studies). Health-related quality of life (HRQoL) was assessed in 48 studies using a variety of instruments. Substantial HRQoL impacts were consistently demonstrated, reported by adults with CKD; higher CKD stages and presence of diabetes were associated with greater impacts. Caregivers: From 5,909 citations, 7 studies were included. Caregivers were primarily female (64–100%); 24–70% were the care recipient’s spouse/partner; and mean age ranged from 47 to 59 years. Time spent caregiving ranged from 27 to 38 h/week (2 studies) and caregiving duration was approximately 4 years (3 studies). Depression and anxiety were reported in 21–36% and 32–44% of caregivers, respectively (2 studies). Although various instruments were used to measure caregiver burden and HRQoL, studies consistently documented the high impact on caregivers (6 studies).
conclusionThis review demonstrates the considerable burden experienced by adults with CKD and their informal caregivers, and highlights several gaps in characterizing these impacts, particularly for economic burden among adults with CKD, and economic and humanistic burden among caregivers. Further research is needed to better describe and quantify these impacts, as well as evaluate modifiable risk factors that contribute to greater burden.
