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

backgroundReproductive failure, determined as recurrent spontaneous abortions (RSA) or recurrent implantation failure (RIF) in women is not well understood. Several factors, including embryo quality, and cellular and molecular changes in endometrium may contribute to the insufficient feto-maternal interaction resulting in reproductive failure. Prior clinical studies suggest an inadequate endometrial growth and development of the endometrium, leading to a lesser endometrial thickness.

methodsWe therefore aimed to determine the cellular proliferation using Ki67, and the expression of markers of vascularisation, such as factor VIII (a marker of endothelial cells) and smooth muscle cell actin (SMCA; a marker of pericytes and smooth muscle cells) in endometrium of healthy women and women with RSA or RIF. LH-dated mid-secretory endometrial biopsies of seven healthy women and twenty women with reproductive failure were examined via immunohistochemistry followed by image analysis.

resultsCellular proliferation but not expression of factor VIII or SMCA was decreased (P < 0.0004) in endometrium of women with RSA and RIF compared to healthy controls.

conclusionOur data indicate that reproductive failure is due to insufficient cell proliferation/tissue growth rather than inadequate vascularisation in the endometrium.
