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
Mammalian sperm cells must undergo several processes collectively called capacitation before carrying out the acrosome reaction (AR), which is required for sperm penetration into the oocyte. The spontaneous acrosomal reaction (SAR), which can occur before the sperm cell reaches the vicinity of the oocyte, impairs the fertilizing ability of the sperm. This study examined the role of the Fer tyrosine kinase in sperm fertilizing activity. Inhibition of the Fer activity led to a 75% reduction in IVF rates in mice, indicating a critical role for Fer in fertilization. Further investigation of Fer's role during sperm capacitation focused on its potential interaction with the epidermal growth factor receptor (EGFR). Inhibition of Fer during capacitation significantly decreased the EGFR activation state and increased the incidence of SAR, whereas inhibition of Fer during the acrosome reaction step had no effect on the EGF-induced AR. The effects of Fer inhibition on EGFR activation and SAR enhancement are mediated by the Ca
