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

We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of TZDs in treatment of diabetes mellitus patients with renal impairment. We searched PubMed, EMBASE and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs), cohort studies, and case-control studies that investigated the effects of TZDs in patients with diabetes and renal impairment were eligible. Outcomes included glycosylated hemoglobin, fasting plasma glucose, serum lipids, and patient-important outcomes (i.e. hypoglycemia, weight, edema, cardiovascular events and mortality). 19 RCTs and 3 cohort studies involving 21,803 patients with diabetes and renal impairment were included. Meta-analysis of RCTs showed that TZDs could significantly reduce HbA1c (MD -0.64, 95%CI -0.93 to -0.35), FPG (MD -26.27, 95%CI -44.90 to -7.64) and increase HDL levels (MD 3.70, 95%CI 1.10, 6.29). TZDs could increase weight (MD 3.23, 95% CI 2.29 to 4.16) and risk of edema (RR 2.96, 95% CI 1.22 to 7.20). Their effects on risk of hypoglycemia (RR 1.46, 95% CI 0.65 to 3.29), heart failure (RR 0.64, 95% CI 0.15 to 2.66), angina (RR 1.45, 95% CI 0.23 to 8.95) and all-cause mortality (RR 0.40, 95% CI 0.08 to 2.01) are uncertain. Results from cohort studies were similar to RCTs.
