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 aim of the present study was to evaluate the efficiency of using in vitro fertilization to validate semen fertility for artificial insemination. Cryopreserved semen from ten bulls (five Nelore and five Brangus bulls) was evaluated using in vitro production of embryos (IVPE) and via fixed-time artificial insemination (FTAI). There was variation (p < 0.05) in the IVPE (20.9 to 53.7% of blastocyst production) and in the FTAI (42.0 to 56.0% of pregnant cows) results among the semen evaluated. According to the results, there was a positive correlation (rs = 0.8378; p = 0.0001) between the rate of blastocyst production (using IVPE) and the rate of pregnancy (using FTAI) using Nelore bull semen. Variation (p < 0.05) was also found using semen from Brangus bulls, in the rates of blastocyst production (36.5 to 47.0%) and pregnancy (45.6 to 52.2%) via FTAI. There was also a positive correlation (rs = 0.8786; p = 0.0001) between the rates of blastocyst production (IVPE) and pregnancy (FTAI) when using Brangus bull semen. According to the results, IVPE may be used in addition to conventional semen analysis to evaluate and validate the semen fertility of bulls for artificial insemination programs.
