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

Guanidinoacetic acid (GAA) increases milk production in dairy cows by promoting milk fatty acid (FA) and protein synthesis; however, its mechanism is unclear. It was hypothesized that provision of rumen-protected GAA (RPGAA) would increase milk production, and milk fat and protein synthesis, while revealing the underlying mechanisms. Forty-four multiparous Holstein dairy cows (33.5 ± 1.31 kg/d of milk yield, 667 ± 11.8 kg of body weight, and 38.5 ± 2.14 d in milk [DIM]) were blocked by daily milk yield and DIM, and allocated to different treatments in a randomized-block design, namely, the control (without RPGAA), low-RPGAA (0.18 g/kg DM of GAA), medium-RPGAA (0.36 g/kg DM of GAA), and high-RPGAA (0.54 g/kg DM of GAA) groups. The experiment lasted for 95 d, including a 10-d covariate period, a 15-d adaptation period, and a 70-d sampling period. Although the DM intake and BW were not impacted (
