Preterm birth.
Synthesis in BMJ clinical evidence, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 2 of them syntheses that pooled 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.
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.
Who cites it
8 citing papers in PubMed, 2 syntheses or guidelines pooled it, 9 citations in OpenAlex.

Abstract
introductionPreterm birth occurs in about 5% to 10% of all births in resource-rich countries, but in recent years the incidence seems to have increased in some countries, particularly in the USA. We found little reliable evidence for incidence in resource-poor countries. The rate in northwestern Ethiopia has been reported to vary from 11% to 22%, depending on the age group of mothers studied, and is highest in teenage mothers. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of preventive interventions in women at high risk of preterm delivery? What are the effects of interventions to improve neonatal outcome after preterm rupture of membranes? What are the effects of treatments to stop contractions in preterm labour? What are the effects of elective compared with selective caesarean delivery for women in preterm labour? What are the effects of interventions to improve neonatal outcome in preterm delivery? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
resultsWe found 58 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
conclusionsIn this systematic review, we present information relating to the effectiveness and safety of the following interventions: amnioinfusion for preterm rupture of membranes, antenatal corticosteroids, antibiotic treatment, bed rest, beta-mimetics, calcium channel blockers, elective caesarean, enhanced antenatal care programmes, magnesium sulphate, oxytocin receptor antagonists (atosiban), progesterone, prophylactic cervical cerclage, prostaglandin inhibitors (e.g., indometacin), selective caesarean, and thyrotropin-releasing hormone (TRH) (plus corticosteroids).
