Trajectories of kidney function over 10 years in patients with chronic kidney disease: a 10 year follow-up of FROM-J study.
Article in Clinical and experimental nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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 frontier of renal outcome modifications in Japan 10 (FROM-J10) study is a 10 year longitudinal cohort study evaluating the long-term outcomes of treatment according to the clinical guidelines for chronic kidney disease (CKD) by primary care physicians. This study aimed to identify distinctive trajectories of kidney function among patients with CKD and evaluate the patient characteristics associated with each trajectory using the FROM-J10 study data.
methodThis secondary study used 10 years of data from 2379 patients aged between 40 and 74 years with CKD stages from G1 to G5 in the FROM-J10 study. Group-based trajectory modeling was applied to the change in estimated glomerular filtration rate (eGFR) over time, and patients were classified into distinct groups that followed similar trajectories. Multivariate logistic analysis was performed for patient characteristics associated with each trajectory.
resultsIn total, 2257 patients with at least three eGFR values were included in this study. Two distinct trajectories of eGFR decline were identified: progressive decline (n = 1240, 54.9%) and gradual decline (n = 1017, 45.1%). In multivariate logistic analysis with gradual eGFR decline as a reference, proteinuria was associated with progressive eGFR decline in CKD from G2 to G4 + 5; lower albumin in G2, G3a, and G4 + 5; and lower hemoglobin in G3a to G4 + 5.
conclusionsIn patients with CKD adequately treated by primary care physicians, kidney function declined very slowly over 10 years. We suggest that patient characteristics identified as progressive eGFR decline, proteinuria, and lower albumin and hemoglobin levels should be managed appropriately in clinical practice.
