1 · What the graph read from it

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.

2 · The registry

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

backgroundDiabetes mellitus (DM) is a major cause of end-stage kidney disease (ESKD). However, the difference in renal outcomes between DM patients with non-diabetic renal disease (DM and NDRD) and those with diabetic nephropathy (DN) is controversial. The aim of the present study was to evaluate the differences among patients with DN, DM, and NDRD, and non-DM chronic kidney disease (CKD) in a prospective observational study.

methodsWe extracted the data of 2484 patients from 11 nephrology care centers and categorized into three groups as described above. The primary outcome was ESKD requiring renal replacement therapy.

resultsDuring the median follow-up of 4.44 years, 281 patients (11.3%) developed ESKD. Renal outcomes of DM and NDRD patients were similar to those of non-DM patients (p ≥ 0.05). At CKD stage G3b, the hazard ratios (95% confidence intervals) of ESKD were 7.10 (2.46-20.49) in DN patients and 0.89 (0.19-4.24) in DM and NDRD. The annual change in the estimated glomerular filtration rate (eGFR) in DN patients was significantly larger than that in other groups at stage G3b (-9.7%/year).

conclusionsWe found that DN patients have a higher risk for ESKD than DM and NDRD or non-DM patients. In particular, GFR rapidly declined in DN at stage G3b. DM and NDRD patients can accomplish equally beneficial renal outcomes as non-DM CKD, regardless of their similar metabolic profiles as DN. In conclusion, we should prudentially consider the risk stratification of DM whether cause or comorbidity of CKD.
