Utility of urinary netrin-1 levels in patients with type 2 diabetic nephropathy and its correlation with renal function.

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
purposeNetrin-1 is a urinary protein that may help in the diagnosis of diabetic nephropathy. The objectives of this study were to assess urinary netrin-1 levels in patients with type 2 diabetic nephropathy and to determine its correlation with renal function among them. METHODOLOGY: This cross-sectional analytical study was conducted at a tertiary care teaching hospital in south India for 18 months. Study subjects were divided into four groups: non-diabetics, diabetics with normal to mildly increased albuminuria, moderately increased albuminuria, and severely increased albuminuria. Urinary albumin was quantified by nephelometry for all study subjects. The ELISA technique estimated urinary netrin-1 levels in all groups.
resultsUrinary netrin-1 levels were higher in diabetic subjects with normal to mildly increased and severely increased albuminuria than in the control group. Correlation analysis showed that there was a positive correlation of urinary netrin-1 with urinary albumin-creatinine ratio (UACR) and no correlation with estimated glomerular filtration rate (eGFR). Urinary netrin-1 showed a sensitivity of 88.3% and specificity of 75% at a cut-off value of 889.74 pg/mg creatinine for diagnosing diabetic nephropathy.
conclusionUrinary netrin-1 levels were elevated in diabetic subjects with moderately and severely increased albuminuria as compared to non-diabetic subjects. It showed a positive correlation with the urinary albumin-creatinine ratio and no correlation with eGFR in diabetic subjects.
