Urinary alpha- and pi-glutathione s-transferases in adult patients with type 1 diabetes.
Article in Nephron extra, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
BACKGROUND/
aimsGlutathione S-transferases (GSTs) are cytosolic enzymes excreted from renal tubules following tubular damage. α-GST primarily originates from proximal tubules, while π-GST from distal tubules and collecting ducts. We investigated if GST levels are associated with renal function in patients with type 1 diabetes.
methodsWe conducted a cross-sectional study including 189 Caucasian patients with type 1 diabetes and 16 nondiabetic controls. α- and π-GST were measured by ELISA and reported as GST/urinary creatinine excretion (μg/mmol).
resultsThe subjects were 53 ± 14 years old, 66 (35%) were female and the estimated glomerular filtration rate was 85 ± 29 ml/min/1.73 m(2). Normo- (<30 mg/24 h), micro- (30-299 mg/24 h) and macroalbuminuria (≥300 mg/24 h) was present in 57, 61 and 71 patients, respectively. α- and π-GST/creatinine ratios in controls versus all patients were 0.07 (0-0.3) and 0.11 (0-0.8) μg/mmol versus 0.05 (0-2.3) and 0.16 (0-4.9) μg/mmol (p ≥ 0.16; adjusted for age and gender, p ≥ 0.18). The α-GST/creatinine ratio positively correlated with female gender (p = 0.04), while the π-GST/creatinine ratio was associated with age and female gender (p ≤ 0.016). Comparing normo-, micro- and macroalbuminuric patients, α- and π-GST levels were similar (p = 0.10; adjusted p = 0.11). Neither α- nor π-GST levels were significantly associated with renal function (p ≥ 0.34).
conclusionα- and π-GST/creatinine ratios were similar among controls and patients with type 1 diabetes. In addition, we did not find associations with albuminuria degree or level of renal function. The significance of increased or decreased excretion of α- and π-GST among patients with diabetes needs to be clarified.
