Anti-oxidative enzymes, cardiovascular disease risk factors, and adipokines in Nigerian women on oral and implant contraceptives.

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: Increased use of oral contraceptives and implants has necessitated the need to examine biochemical changes associated with their use. Objectives: This study assessed insulin resistance, lipid profile, superoxide dismutase, glutathione peroxidase, adiponectin and leptin levels in women using oral and implant contraceptives in Calabar. Methods: Ninety women aged 18-45years were recruited for this case-control study. Thirty of them women were on oral contraceptives, 30 on implants and the remaining 30 were controls. Total cholesterol (TC), VLDL-cholesterol (VLDL-C), HDL-cholesterol (HDL-C), triglycerides, glucose, insulin, superoxide dismutase, glutathione peroxidase, adiponectin and leptin were analyzed by standard methods. Body mass index (BMI), Insulin resistance (HOMA-IR), Atherogenic index of plasma (AIP) and LDL-cholesterol (LDL-C) were calculated. Data was analyzed by Multivariate Analysis of Variance, Bonferrori Post Hoc test and Pearson's correlation.Significance was set at <0.05. Results: The oral contraceptive users had significantly higher BMI (p=0.003), TC (p=0.004), HDL-C (p=0.000), Insulin (p=0.019), Leptin (p=0.000) and Adiponectin (p=0.049) than controls. Implant users had a significantly higher (p=0.000) BMI, TC, HDL-C LDL-C, Insulin, HOMA-IR, FPG (p=0.018) and Leptin (p=0.022) with significantly lower TG (p=0.003), VLDL-C (p=0.000) and AIP (p=0.003) compared to controls. There was a significant positive correlation between the duration of contraceptive use with LDL-C in implant users (r=0.366, p=0.046). Conclusions: Oral contraceptive use may be associated with weight gain while implant use may lead to derangement in carbohydrate, lipid metabolism and weight gain. This suggests the need for appropriate client profiling before recommending a contraceptive method, especially for those with pre-existing conditions.
