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
purposeIndividuals with diabetes and chronic kidney disease are at high risk of kidney failure, cardiovascular events and premature mortality and more research is warranted to further improve the prevention and management of complications. The PRecIsion MEdicine based on kidney TIssue Molecular interrogation in diabetic nEphropathy (PRIMETIME) 1 cohort is designed to study clinical characteristics, diagnostic accuracy and prognostic markers in a population with diabetes and kidney disease classified by biopsy.
participantsThis retrospective Danish nationwide cohort includes 2586 individuals with diabetes who have undergone a kidney biopsy between the 1980s and 2022. FINDINGS TO DATE: By combining multiple registries and medical databases, we comprehensively describe the cohort with data on demographics, socioeconomic status, lifestyle, laboratory measurements, medication use and comorbidity at the time of diagnosis of diabetes and at the time of kidney biopsy within types of kidney disease. In individuals with type 1 diabetes, 132 cases of diabetic nephropathy were identified, with 70.5% of them being men, with a median (IQR) age of 50 (41-59) years at biopsy, and a median (IQR) estimated glomerular filtration rate (eGFR) 37 (23-5X) mL/min/1.73 m FUTURE PLANS: The national population registries in Denmark provide a long follow-up period and a distinct opportunity to use superior registry data. This cohort offers a unique opportunity to study the prognostic value of findings in kidney biopsies, the impact of comorbidity and the effect of therapy at the time of kidney biopsy, with a follow-up period increasing over time with running updates.
