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
The present study was designed to investigate the effects of amino acid (histidine and L-Tyrosine) on in vitro maturation (IVM), in vitro fertilization (IVF), cleavage (CR) rates, and in vitro embryonic cultivation (IVC; Morula and Blastocyst stage) in buffaloes. Within two hours of buffalo slaughter, the ovaries were collected and transported to the laboratory. Follicles with a diameter of 2 to 8 mm were aspirated to recover the cumulus oocyte complexes (COCs). Histidine (0.5, 1, and 3 mg/ml) or L-Tyrosine (1, 5, and 10 mg/ml) were added to the synthetic oviductal fluid (SOF) and Ferticult media. The IVM, IVF, CR, and IVC (Morula and Blastocyst) rates were evaluated. The results showed that SOF maturation media containing histidine at 0.5 mg/ml significantly (P ≤ 0.01) improved the oocyte maturation when compared to control and other concentrations. The addition of histidine to FertiCult media at 0.5, 1, and 3 mg/ml did not improve the IVM, IVF, CR, or IVC percentages. However, the embryos in the control group were unable to grow into a morula or blastocyst in the SOF or Ferticult, while addition of L-Tyrosine to the SOF or Ferticult at various concentrations improved IVC (morula and blastocyst rates). There was a significant (P ≤ 0.01) increase in IVM when histidine was added to SOF medium at a concentration of 0.5 mg/ml compared with L-Tyrosine. Also, there were significant (P ≤ 0.01) increases in IVC when L-Tyrosine was added to SOF medium at concentrations of 1 and 10 mg/ml compared with histidine. In conclusion, the supplementation of the SOF and FertiCult with the amino acids histidine and L-Tyrosine improve the maturation rate of oocytes and development of in vitro-produced buffalo embryos.
