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
We determined whether androgen deficiency induced by flutamide treatment during mid- and late pregnancy affects the functions of the porcine corpus luteum (CL). Pregnant gilts were injected with flutamide between days 43 and 49 (gestation day [GD] 50F), days 83 and 89 (GD90F), or days 101 and 107 (GD108F) of gestation. Antiandrogen treatment increased the luteal progesterone concentration in the GD50F group and decreased progesterone content in the GD90F and GD108F groups. Luteal levels of side-chain cleavage cytochrome P450 (CYP11A1) mRNA and protein were significantly downregulated in the GD90F and GD108F groups as compared with the respective controls. The 3β-hydroxysteroid dehydrogenase/Δ5-Δ4 isomerase (HSD3B) mRNA and protein expression were significantly reduced only in the GD108F group as compared with the control. Decreased luteal 20α-hydroxysteroid dehydrogenase (AKR1C1) mRNA and protein levels were observed in the GD50F group. Thus, androgen deficiency during pregnancy in pigs led to CL dysfunction that is marked by decreased progesterone production. Furthermore, exposure to flutamide during late pregnancy downregulated steroidogenic enzymes (CYP11A1 and HSD3B) in pigs. We conclude that androgens are important regulators of CL function during pregnancy.
