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

We, in this manuscript, address the fact that increasing numbers of published studies in reproductive medicine selectively report outcomes for only favorably selected patients; while failing to note that, so reported outcome data,therefore, cannot be applied to unselected patient populations. Almost all favorable patient selection methods, starting with prolonged embryo culture to blastocyst stage, have, thus, been widely misrepresented in the literature since they almost universally report outcomes only in reference to embryo transfer. These outcome reports, however, do not include outcomes for poorer prognosis patients who do not reach embryo transfer. Study outcomes are universally applicable only if performed in unselected patient populations and reported with reference point cycle start (intent to treat). All other studies greatly exaggerate clinical pregnancy and live birth rates if applied to general populations, unless specifically noting that they can be extrapolated only to women who reach embryo transfer.
