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

Genital bacterial infection is one of the most important causes of infertility, however, bacteria frequently exist in seminal fluid. Sperm express Toll-like receptors (TLRs) on their cell surfaces and bacterial recognition by TLRs induces sperm apoptosis. In this study, we examined the lactoferrin (LF) potentiality on sperm apoptosis induced by bacterial lipopolysaccharide (LPS). The TdT-mediated dUTP-biotin nick end labeling (TUNEL) assay indicated that TUNEL-positive sperm cells were scarce in the group treated with LF and LPS (LF/LPS group) compared to the group treated with LPS only (LPS group). In addition, real-time RT-PCR detected lower mRNA expression levels of apoptosis-associated genes in the LF/LPS group compared to the LPS group. These results indicate that LF treatment of semen might decrease LPS-induced apoptosis of sperm.
