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

Objective: We aimed to investigate whether advanced maternal age is associated with cesarean delivery in nulliparous individuals undergoing elective induction of labor (eIOL). Study Design: We queried a multicenter outpatient electronic medical record to perform a retrospective cohort study of nulliparous individuals undergoing eIOL between 39 Results: Of the 84,156 eligible individuals, 932 met our inclusion criteria, with 728 (78.1%), 141 (15.1%), and 63 (6.8%) with age <35 years, 35-39 years, and ≥40 years, respectively. We found an increased incidence of cesarean delivery with increasing age (25.8% for age <35 years, 41.1% for age 35-39 years, and 55.6% for age ≥40 years, Conclusion: Our findings highlight an association between increasing maternal age and cesarean delivery among nulliparous individuals undergoing eIOL. Further studies should determine whether biologic or immunologic factors play a role or whether altered labor management may improve these outcomes. Key Points: · Among patients undergoing eIOL, increased age is associated with cesarean delivery.. · After adjusting for confounders in multivariable regression, age remained associated with cesarean delivery.. · Future studies are needed to determine the etiology of increased cesarean delivery with maternal age..
