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

purposeRecurrent pregnancy losses (RPL) are considered a pathological condition associated with heterogeneous laboratory and clinical findings, and are also linked to subfertility. We attempt to rank parameters derived from past history and diagnostic results with regard to the prognosis.

methodsObservational trial on 719 consecutive couples who were referred to a tertiary immunological care centre (2006-2014) after three or more primary miscarriages. Information on past obstetric history and diagnostic procedures at baseline were correlated with cumulative pregnancy and delivery rates using Kaplan-Meier estimation, logistic regression and multivariate analysis.

resultsAt baseline, median female age was 34.1 years, waiting time 3 years (1-17), number of preceding miscarriages 3 (3-9), 147 women (20.4%) had conceived at least once in ART or AIH cycles. After a median follow-up of 33.7 (1.7-123.0) months, 5-year pregnancy and delivery rates were 86.1 and 64.5%. Female age (< 35 years), waiting time (< 3 years) until baseline, tubal competence, and male factor fertility significantly correlated with favourable outcome (p < 0.001), while body mass index (> 29 kg/m

conclusionAlthough in general, chances to conceive a child are retained after three or more miscarriages, factors related to subfertility of both partners have an important impact on the outcome. Therefore, prolonged time to pregnancy (> 6-9 months) should result in preventive gynaecological care from the first miscarriage on, so that fertility can be preserved as best as possible.
