Trial reportThe review of diabetic studies : RDS
Paradoxical negative HDL cholesterol response to atorvastatin and simvastatin treatment in Chinese type 2 diabetic patients.
Trial report in The review of diabetic studies : RDS. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 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.
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
objectivesThere is extensive but controversial evidence on the diverse effects of statins on the level of high-density lipoprotein cholesterol (HDL-C). Some of these effects may limit the benefits of statins in terms of cardiovascular risk reduction. To identify the conditions for beneficial effects, this study investigated the response to atorvastatin and simvastatin treatment in type 2 diabetic patients with elevated low-density lipoprotein cholesterol (LDL-C).
methods2,872 subjects with type 2 diabetes from a disease management program were investigated. Patients with LDL-C ≥130 mg/dl or total cholesterol ≥200 mg/dl were put onto statin therapy by the National Health Insurance system in Taiwan.
results1,080 patients who completed 1 year of statin treatment were analyzed. There were significant reductions in LDL-C in both the atorvastatin (37.1%) and simvastatin (34.3%) group after one year of treatment compared with baseline levels. Unexpectedly, the majority of diabetic patients who received atorvastatin or simvastatin did not show an increase in HDL-C levels. 59.8% of patients had a significant HDL-C reduction (ΔHDL-C ≤ -3%) after atorvastatin treatment. Multivariate logistic regression analysis showed that the following patients were at higher risk of HDL-C reduction after 12 months: (i) patients in whom statin therapy was initiated aged <65 years and who had a BMI ≥24 kg/m(2), (ii) male patients with a baseline HDL-C >40 mg/dl, and (iii) female patients with a baseline HDL-C >50 mg/dl. However, diabetic patients with severe atherogenic dyslipidemia (LDL-C ≥130, TG ≥204, and HDL-C ≤34 mg/dl) obtained more benefits in terms of HDL-C change after statin therapy.
conclusionsDiabetic patients, except those with severe atherogenic dyslipidemia, are prone to a decrease in serum HDL-C level after statin treatment, particularly after atorvastatin treatment.
