Characteristics and outcomes associated with multiple triage visits among patients with suspected preterm labor or preterm premature rupture of membranes.
Article in AJOG global reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.

Abstract
Background: Hospital-based obstetrical triage units frequently serve as an extension to outpatient care. Evaluation of the burden of preterm birth (PTB) typically focuses on the delivery and neonatal periods, while antepartum health care utilization related to risk of PTB is seldom reported. Objective: To identify the characteristics and outcomes associated with multiple triage visits among patients with suspected preterm labor (PTL) or preterm premature rupture of membranes (pPROM). Study Design: Secondary analysis of a retrospective cohort study of all triage visits from 20 0/7 through 34 6/7 weeks gestation on randomly selected dates in 2019 at 34 hospitals across the US. Those in whom the reason for the visit was suspected PTL or pPROM and who were subsequently discharged were eligible for this analysis. Patients with ≥3 triage visits were compared with those who had <3 visits in the index pregnancy visits. Data were abstracted by certified research personnel using predefined criteria. The primary outcome was a composite of severe neonatal morbidity or mortality before 120 days. Secondary outcomes included PTB (<37 weeks gestation), a composite of respiratory neonatal morbidities, and maternal outcomes. Multivariable logistic regression analyses were used for the maternal outcomes, and generalized linear and logistic models were used for the neonatal outcomes to account for the correlation among twins. Results: A total of 1764 mother/newborn dyads were included. Patients with more frequent triage visits (≥3) were more likely to self-identify as Black, be younger, not married/living with a partner, unemployed, have government-assisted insurance, or have less than a college degree compared to those individuals with less frequent triage visits ( Conclusion: In this multisite registry of triage visits with rigorous ascertainment and data collection, multiple visits (≥3) for suspected PTL or pPROM were not associated with differences in maternal or neonatal outcomes.
