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

purposeHuman papillomavirus (HPV) has been shown to disrupt late-stage implanting embryos. The objectives were (a) to assess the development of early embryos exposed to HPV DNA and (b) to analyze the blastocyst hatching process after HPV exposure.

methodsThe study involved exposing two-cell and 4-8-cell mouse embryos to DNA fragments from either HPV type 16, type 18 or DQA1 (control). The embryos were incubated for 120 h and assessed.

resultsHPV 16 and 18 inhibited two-cell embryo development. In contrast, delaying the exposure of HPV DNA until the 4-8-cell stage resulted in further embryonic development. There was 25.9% less blastocyst formed with HPV 16 exposure. Additionally, there were 25.9-31.8% more degenerated embryos with HPV 16 exposure.

conclusionsThe study demonstrated embryo stage-specific effects of HPV on early development. The results suggested HPV exposure was linked to two-cell embryo demise and delaying the exposure of HPV until later embryo stages permitted embryo development. HPV 16 was shown to decrease blastocyst formation while HPV 18 inhibited the blastocyst hatching process.
