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

This paper reports on the numbers of treatment cycles involved in the development of IVF (1969-1978) and their outcomes. We show that between 1969 and 1978: (i) a minimum of 282 women were involved in 495 cycles of potential laparoscopic oocyte retrieval (LOR); (ii) of these cycles, 457/495 proceeded to LOR to attempt egg collection; (iii) of which an outcome was recorded in 436/457; (iv) eggs were recovered in 388/436 of these; (v) inseminations were recorded in 331/388; (vi) embryos were recorded in at least 167; (vii) a total of 112 embryo transfers were attempted; and (viii) a maximum of 11 possible biochemical/preclinical pregnancies plus five clinical pregnancies were observed; (ix) from which two healthy live births resulted.
