The delay of motherhood: Reasons, determinants, time used to achieve pregnancy, and maternal anxiety level.
Observational study in PloS one, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 34 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.

Abstract
backgroundFertility in recent decades in European countries such as Norway, Spain or United Kingdom has declined, while in others such as Portugal, it has remained relatively constant, and in others such as Germany fertility rated have risen. The determinants of this change in reproductive pattern can be explained by the cultural, social, and economic changes that took place in our society. Objective: to identify the principal reasons and independent determinants associated with the postponement of motherhood and document any association between the time taken to achieve successful pregnancy and maternal age, as well as the level of anxiety of these women.
methodsAn observational study, including 326 women, was conducted in Spain with primiparous women, in which data was collected on sociodemographic, health, and pregnancy-related factors. Comparison of means (t-test or analysis of variance) and the analysis of covariance was used to estimate adjusted means for potential confounders.
resultsWomen in stable relationships became mothers at older ages (31.83±0.29) than those who were not (28.75±0.78) (p<0.001). Women who delayed motherhood for medical reasons had a mean age of 34.15 ± 0.88 years, compared to a mean of 30.52±0.36 years for personal reasons, and 27.51±1.39 years for other reasons. Mothers with an older age had a higher level of anxiety (p<0.05). The average time required to achieve pregnancy increased as maternal age increased, with an average time of 24 months for women with a mean age of 35.23±0.71 years compared to <3 months for women with a mean age of 29.44±0.39 years. Women ≥ 35 years were more likely to need medical assistance to achieve pregnancy (aOR = 12.07, 95% CI: 1.50-97.05; p = 0.019).
conclusionsMedical reasons were among those cited for delaying motherhood. The postponement of motherhood was associated with difficulty to achieve a successful pregnancy and a higher level of anxiety.
