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

Postpartum contraception is an important step for preventing closely spaced pregnancy. Combined oral contraceptive (COC) has been linked to cardiometabolic disturbances. We therefore hypothesized that postpartum oral estrogen-progestin use induces hepatic lipid accumulation that is associated with glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) activation via adenosine deaminase (ADA)/xanthine oxidase (XO)/uric acid (UA)-dependent pathway. Female Wistar rats weighing 130-150 g were mated to achieve timed pregnancy and delivery. Twenty-four (24) dams were randomly assigned to receive vehicle (po), COC (1.0 μg ethinylestradiol and 5.0 μg levonorgestrel; po), COC with GR blockade (mifepristone; 80.0 mg/kg; po) and COC with MR blockade (spironolactone; 0.25 mg/kg; po) daily between 3rd and 11th week postpartum. Data showed that postpartum COC resulted in glucose dysregulation, increased visceral adiposity, liver weight, plasma corticosterone, aldosterone, circulating and hepatic free fatty acid (FFA), triglyceride (TG), adenosine deaminase (ADA), uric acid production, lactate production, and oxidative marker injury. On the other hand, G6PD-dependent antioxidant defenses were depressed by postpartum COC. However, these effects were attenuated by GR or MR blockade. Our data demonstrate that enhanced G6PD-dependent antioxidant defenses and suppressed ADA/XO/UA pathway in the liver by GR or MR blockade improves glucose dysregulation and hepatic TG accumulation induced by postpartum COC. This study implies a plausible involvement of GR and MR via defective G6PD-dependent antioxidant barrier and increased activity of ADA/XO/UA pathway in postpartum COC-induced hepatic lipid accumulation.
