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

backgroundHyperhomocysteinemia is an independent risk factor for cardiovascular events. The aim of this study was to show the results of the reduction of homocysteine in end stage renal failure patients on hemodialysis, as it is known, have higher levels of homocysteine than other groups of subjects.

methodsPlasma homocysteine concentration was determined before and after the administration of vitamin B6 and folic acid in 12 patients (males: 6) on regular dialysis therapy. Mean monthly fasting serum concentrations of total cholesterol (TCHOL), HDL-chol, LDL-chol and triglycerides (TRG) were determined for a period 68 months (12-120 months) before and 26 months after the administration of vitamin B6 and folic acid.

resultsMean serum concentrations for folic acid and vitamin B12 before and after the administration were: folic acid: 5.03 +/- 4.9 and 18.0 +/- 19.2 ng/mL, (p < 0.0001) and B12: 456 +/- 257 and 514.38 +/- 307 pg/mL respectively). Plasma homocysteine was reduced significantly after the administration of above drugs (from 47 +/- 14 to 29 +/- 9 micromol/mL, p < 0.001). This reduction of homocysteine resulted in a modification of the patients' lipidemic profile: Serum LDL-chol was decreased significantly (119 +/- 38 mg/dL to 110 +/- 35 mg/dL, p<0.005). TCHOL and TRG were also decreased but not significantly (190 +/- 45 mg/dL to 187 +/- 43 mg/dL and 116 +/- 63 mg/dL to 108 +/- 47 mg/dL respectively)). Serum concentrations HDL-chol were increased significantly (from 42 +/- 10 mg/dL to 47 +/- 10 mg/dL, p < 0.001). The atherogenic index for cholesterol, LDL/HDL, was 1.6 times lower after the drugs receiving (before: LDL/HDL = 3.1 and after: LDL/HDL = 2.5, p < 0.001).

conclusionsThese results indicate that the folate and vitamin B6 supplementation resulted in reduction of homocysteine levels and improvement of lipidemic profile in regular dialysis patients.
