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

Purpose: ML-2-3 is a novel tetracyclic iridoid derived from Methods: IVF was performed using sperm from BALB/cByJJcl mice treated with ML-2-3. Computer-assisted sperm analysis (CASA) was performed on the sperm of C57BL/6J mice to investigate sperm motility. The effect of ML-2-3 on the acrosome reaction was examined by observing the fluorescence of sperm labeled with the acrosin-EGFP transgene. Results: ML-2-3 improved IVF in BALB/cByJJcl mice with low fertilization rates. The optimum concentration of ML-2-3 in sperm pre-culture medium was 20 Conclusions: ML-2-3 can improve the outcome of IVF and motility without inducing the acrosome reaction in mice. These effects of ML-2-3 on sperm behaviors are different from those of the similar drugs.
