Associated factors of first-birth interval among women in reproductive age, addressing maternal and child health.
Article in Reproductive health, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThe first-birth interval directly influences family size and maternal and child mortality. The objective of this study is to investigate factors associated with the time of the first-birth after the first marriage among women in Iran.
methodsIn this cross-sectional study, the first birth history of 1350 women aged 15-49 years was collected in Kerman (southern Iran) in 2018. To assess the predictor variables of the first-birth interval and calculate the adjusted hazard ratios, multivariate Cox regression was used. The P-value < 0.05 was considered as significant. The statistical analysis of data was performed using SPSS version 22.
resultsThe average of the first-birth interval was 2.5 ∓ 0.8 years. Woman's age at marriage (HR 1.48, 95% CI 1.32-2.48), husband's age at marriage (HR 1.88, 95% CI 1.62-2.03), age at the first menstruation (HR 1.53, 95% CI 1.24-2.53), being rural residents (HR 2.041, 95% CI 1.26-2.95), and having engagement period (HR 1.85, 95% CI 1.52-3.05) were associated with short first-birth interval, and woman's BMI (HR 1.72, 95% CI 1.54-2.77), woman's university educational level (HR 1.47, 95% CI 1.35-2.57), husband' s university educational level (HR 1.39, 95% CI 1.32-2.51), contraception use (HR 2.28, 95% CI 1.12-2.86) and income sufficiency (HR 2.25, 95% CI 1.12-2.96) were associated with long first-birth interval.
conclusionsBeing a rural resident is the most influential predictor of short first-birth interval and income sufficiency is the most influential predictor of long first-birth interval.
