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

backgroundIn recent studies, partial deletions of the azoospermia factor c region (AZFc) on the Y-chromosome have been detected in males with infertility problems. However, there has been a lot of debate about their significance. In order to study such deletions, a simple but accurate method for their detection was applied in this study.

methodsWe present data obtained from the Multiplex Ligation-dependent Probe Amplification (MLPA) assay using a new Y-chromosome-specific MLPA probemix (P360) which allows the easy detection of partial AZFc deletions.

resultsPartial AZFc deletions were detected in 8% of our cohort of previously mutation-negative infertile males (and 0% of the fertile control cohort).

conclusionThese results provide further evidence of the causality of partial AZFc deletions. None of the partial AZFc deletions were detectable by the standard multiplex PCR method, demonstrating the advantage of the MLPA method.
