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

The objective of this study was to evaluate the impact of grazing pastures with low (Low group) and high (High group) percentages of Epichloë coenophiala-infected tall fescue on ovarian blood flow and activity in beef cows subjected to a Fixed-Time Artificial Insemination (FTAI) protocol. Cows in the Low group (n = 18) grazed for 79 days on a pasture where fescue accounted for 13% of the available forage, with an endophyte infection rate of 96%. Meanwhile, cows in the High group (n = 18) grazed for the same period on a pasture where fescue represented 73% of the available forage, with an endophyte infection rate of 94%. Consumption of pasture with a high percentage of endophyte-infected (E+) fescue was associated with an increase in the rectal temperature, a decrease in the size and the blood flow of the dominant follicle, lower plasma progesterone (P4) concentration, and an increased number of cysts. In addition, the plasma concentration of metabolic hormones, namely triiodothyronine and cortisol, was similar between groups. In conclusion, consuming pastures with a high percentage of endophyte-infected fescue affected the ovarian blood flow and activity without affecting the metabolic hormones in beef cows.
