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
Objectives: To characterize the profile of people with advanced chronic kidney disease treated in specialized outpatient centers and to describe adherence to follow-up and assess the impact of specialized follow-up by comparing the glomerular filtration rate at baseline and after one year of follow-up. Methods: This was a retrospective multicenter study that included people with stage 4 and 5 chronic kidney disease treated between November 2021 and October 2024, in five specialized outpatient centers in Santa Catarina state. The 12-month follow-up rate and changes in kidney function were assessed through the estimated glomerular filtration rate of people who started follow-up by October 2023. Results: Of the 547 people cared for during the study period, 83.0% were at stage 4 of the disease, 80.6% were elderly (>60 years), 91.8% had hypertension, 51.6% had diabetes and 65.6% were overweight or obese. Of the 237 people who started follow-up by October 2023, 211 (90.2%) completed one year of follow-up. The median estimated glomerular filtration rate remained stable during the period (22 [18-26] versus 22 [18-27] ml/min/1.73m2; p-value 0.300). Five people (2.1%) progressed to renal replacement therapy. Conclusion: The population served was predominantly elderly and presented multiple risk factors for progression of chronic kidney disease. The high follow-up rate over one year and the preservation of kidney function reinforced the importance of specialized follow-up in the care of people with advanced chronic kidney disease.
