Trial report in PloS one, 2016. The graph read 3 numbers from its abstract, feeding 2 cells of the map, but none could be read as for or against, so it casts no vote. It is linked to trial NCT01175486 (The Effects of Thiazolidinedione on the Diabetic Retinopathy and Nephropathy), which is not on this map. Cited by 8 papers, 1 of them a synthesis that pooled 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.

Abstract

The marked sentences are the ones the graph read a number from.

objectiveTo assess the effect of pioglitazone on renal outcome, including urinary albumin excretion and estimated glomerular filtration rate (eGFR), in diabetic patients.

designA prospective, randomized, open-labeled, controlled study.

settingTaipei Veterans General Hospital. PATIENTS: Sixty type 2 diabetic patients treated with sulfonylureas and metformin, whose glycated hemoglobin (HbA1c) levels were between 7% and 10% and eGFR was between 45 and 125 mL/min/1.73 m2.

interventionThe patients were randomized to receive acarbose or pioglitazone and followed up for 6 months. Thirty patients were randomly assigned to receive acarbose, and 30 patients were assigned to receive pioglitazone. MEASUREMENTS: The primary study endpoint was the changes in the urinary albumin-to-creatinine ratio (UACR). The secondary endpoint was the changes in eGFR and other parameters.

resultsAfter 6 months of treatment, the mean changes in UACR were -18 ± 104 and 12 ± 85 (p = 0.25, between groups) for the acarbose and pioglitazone groups, respectively. The mean changes in eGFR were 0 ± 14 and -7 ± 16 mL/min/1.73 m2 (p = 0.09, between groups) for the acarbose and pioglitazone groups, respectively. The reductions in HbA1c were similar in both groups. Fasting blood glucose was lower in the pioglitazone group than in the acarbose group. Significant body weight gain was observed in the pioglitazone group as compared with the acarbose group (1.3 ± 2.8 vs. -0.6 ± 1.5 kg, p = 0.002).

conclusionIn type 2 diabetic patients who were treated with sulfonylureas and metformin and possessed HbA1c levels between 7% and 10%, additional acarbose or pioglitazone for 6 months provided similar glycemic control and eGFR and UACR changes. In the pioglitazone group, the patients exhibited significant body weight gain.
