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

objectivesThe aim of this study was to investigate the impact of a history of recurrent ectopic pregnancy (EP) on pregnancy outcomes of subsequent in vitro fertilization (IVF) treatment.

methodsA retrospective cohort study involving 457 women with a history of recurrent EP (REP group), 912 women with a history of single EP (SEP group), and 1169 women with a history of intrauterine pregnancy (IUP group) as the control group, was conducted. IVF outcomes were compared for each cohort.

resultsThe incidence of EP in the REP group after IVF treatment was significantly lower than those in the SEP group (2.4% vs. 6.8%, P = 0.011), and similar to those in the IUP group (2.4% vs. 2.1%, P = 0.830). No significant differences were observed in the clinical pregnancy rate, miscarriage rate, and live birth rate among the three groups. There was no statistically significant difference in the recurrent EP rate between the salpingectomy and salpingostomy treatments. Adjusting for maternal and treatment factors did not influence live birth rates for women with previous REP compared with women with previous SEP and those with IUP. The odds of EP were 82.2% lower (OR 0.178, 95% CI 0.042-0.762; P = 0.020) in women who had blastocyst transfer compared with cleavage embryo transfer in the SEP group. The odds of EP were over six times (OR 6.260, 95% CI 1.255-31.220; P = 0.025) in women who underwent double embryo transfer as opposed to single embryo transfer in the IUP group.

conclusionOur results indicate that women with previous recurrent EP have a lower risk of EP after IVF in comparison with women with previous single EP. Previous EP has no significant adverse effect on the main IVF outcomes. The salpingostomy and salpingectomy treatments of EP do not significantly affect the incidence of recurrent EP after IVF.
