Exercise therapy improves eGFR, and reduces blood pressure and BMI in non-dialysis CKD patients: evidence from a meta-analysis
Open accessAbstract
Background: Patients with chronic kidney disease (CKD) have a high prevalence of cardiovascular diseases, which often lead to physical inactivity that correlates with CKD exacerbation. The benefits of regular exercise to cardiovascular health have been well established in healthy population and highly suggestive in patients with CKD. To further strengthen the evidence base for the management of CKD, this meta-analysis was performed to systematically evaluate the effects of exercise therapy on renal function, blood pressure, blood lipid and body mass index (BMI) in non-dialysis CKD patients. Methods: This meta-analysis was conducted following a previous protocol. Randomized controlled trials (RCTs) examining the effects of exercise therapy in non-dialysis CKD patients were searched in Pubmed, Embase, Cochrane Library, and three major Chinese biomedical databases (CNKI, WANGFANG and VIP) from their start date to October 30th, 2018. The Cochrane systematic review methods were applied for quality assessment and data extraction, and Revman version 5.3 was used for systematic review and meta-analysis. Results: 13 RCTs, representing 421 patients with non-dialysis CKD, were included in this meta-analysis. Compared to the controls, exercise therapy brought an increase in eGFR (MD = 2.62, 95% CI:0.42 to 4.82, P = 0.02, I 2 = 22%), and decreases in systolic blood pressure (SBP) (MD = -5.61, 95% CI:-8.99 to − 2.23, P = 0.001, I 2 = 44%), diastolic blood pressure (DBP) (MD = -2.87, 95% CI:-3.65 to − 2.08, P < 0.00001, I 2 = 16%) and BMI (MD = -1.32, 95% CI:-2.39 to − 0.25, P = 0.02, I 2 = 0%) in non-dialysis CKD patients. Exercise therapy of short-term (< 3 months) decreased triglyceride (TG) level ( P = 0.0006). However, exercise therapy did not significantly affect serum creatinine (SCr), total cholesterol (TC), high density lipoprotein (HDL) or low density lipoprotein (LDL) in non-dialysis CKD patients. Conclusion: Exercise therapy could benefit non-dialysis CKD patients by increasing eGFR while reducing SBP, DBP and BMI. Additionally, short-term intervention of exercise could decrease TG.

TL;DR
This meta-analysis of 13 RCTs in non-dialysis CKD patients found that exercise therapy increased eGFR and reduced systolic blood pressure, diastolic blood pressure, and BMI. It did not significantly affect serum creatinine, total cholesterol, HDL, or LDL overall, though short-term exercise reduced triglycerides.
Key findings
- In 13 RCTs representing 421 non-dialysis CKD patients (experimental/control 212/209), exercise therapy increased eGFR (MD = 2.62, 95% CI 0.42–4.82, P = 0.02, I² = 22%); short-term exercise (<3 months) increased eGFR by 5.22 ml/min/1.73m² (MD = 5.22, 95% CI 0.68–9.77, P = 0.02), but 3–6 months and 6–12 months did not.
- Exercise reduced SBP by 5.61 mmHg (MD = -5.61, 95% CI -8.99 to -2.23, P = 0.001, I² = 44%), DBP by 2.87 mmHg (MD = -2.87, 95% CI -3.65 to -2.08, P < 0.00001, I² = 16%), and BMI (MD = -1.32, 95% CI -2.39 to -0.25, P = 0.02, I² = 0%); BMI reduction was significant with 6–12 months of exercise (MD = -2.27, 95% CI -3.84 to -0.70, P = 0.005) but not <6 months.
- Exercise did not significantly affect SCr (MD = -0.04, 95% CI -0.32 to 0.25, P = 0.79), TC (MD = 1.19, 95% CI -1.60 to 3.99, P = 0.40), HDL (MD = 0.17, 95% CI -0.17 to 0.51, P = 0.32), or LDL (MD = 2.79, 95% CI -1.73 to 7.32, P = 0.23).
- Short-term exercise (<3 months) decreased TG (MD = -94.79, 95% CI -148.81 to -40.76, P = 0.0006), while 3–12 months increased TG (MD = 45.87, 95% CI 17.82 to 73.92, P = 0.001).
Methods
- Systematic review and meta-analysis of RCTs; searched PubMed, Embase, Cochrane Library, CNKI, WANGFANG, and VIP from database start to October 30, 2018, for English or Chinese studies, following PRISMA and Cochrane methods; RevMan 5.3 used for analysis.
- Included adults >18 years with non-dialysis CKD stage 2–5 receiving aerobic and/or resistance exercise at least once weekly for more than one month, with outcomes including eGFR, blood pressure, or blood lipids; 13 RCTs with 421 participants were included.
- Continuous outcomes pooled as mean difference with 95% CI; heterogeneity assessed by χ² test and I²; fixed- or random-effects models used according to heterogeneity; subgroup analyses by exercise duration; sensitivity analysis by leave-one-out; publication bias assessed via funnel plots.
Limitations
- Stated by the authors: included RCT designs were not entirely uniform; randomization and methods were not clearly described; sample size was relatively small; exercise mode, intensity, and frequency were not completely consistent; studies could not be accurately classified by exercise therapy type, so such subgroup analysis was not performed.
- Evident from the text: participant counts are inconsistent across analyses (abstract reports 421 patients, while eGFR analysis reports 529 participants, SBP 463, DBP 399, and BMI 466), and high heterogeneity was present for SCr (I² = 72%), TG (I² = 78%), LDL (I² = 67%), and TC (I² = 54%).
- Evident from the text: performance bias was high in more than 75% of included RCTs because blinding participants and personnel is challenging in exercise trials, and publication bias was assessed only through funnel plot symmetry.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-25, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-25 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
