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
backgroundAdvanced maternal age (AMA), defined as giving birth at age 35 or older, is an increasingly significant public health concern worldwide. This study aimed to identify the socio-demographic and economic determinants of giving birth at AMA among women in Ethiopia and to explore the resulting health consequences for both mothers and children.
methodsThis study is a secondary analysis of data from 5517 women extracted from the 2019 Ethiopian Mini Demographic and Health Survey (EMDHS), a nationally representative cross-sectional survey. The data were cleaned, weighted using STATA V. 17 and analysed using ArcGIS 10.8 to map AMA. Global and local Moran's Index methods were used to assess clustering and a multilevel binary logistic regression model was fitted to identify predictors of giving birth at AMA.
resultsThe prevalence of giving birth at AMA was 12.7%, with a Global Moran's I of 0.9964, indicating significant clustering across Ethiopian zones (p<0.001). Significant individual-level factors associated with higher odds of AMA included male child sex (Adjusted Odds Ratio (AOR)=1.08, p<0.001), fewer smaller family size (AOR=1.02, p<0.001), Catholic (AOR=2.61, p=0.001) and Protestant religion (AOR=1.16, p<0.001), higher household wealth index (AOR=1.02, p<0.001) and residence in Addis Ababa (AOR=2.55) or Amhara (AOR=2.73, p<0.001). Factors associated with lower odds of AMA included no education (AOR=0.69, p<0.001), primary education (AOR=0.56, p<0.001), contraceptive use (AOR=0.99, p=0.0002), rural residence (AOR=0.85, p<0.001), adherence to postnatal check-ups (AOR=0.9453, p<0.001), media exposure (AOR=0.9344, p<0.001) and Afar region residence (AOR=0.81, p<0.001).
conclusionThis study found a high prevalence of giving birth at AMA among women with a lifetime birth history, with a spatially non-random distribution, indicated by a positive Moran's Index. Individual and community-level factors such as having a previous male child, small family size, being Catholic or Protestant and residing in Addis Ababa or the Amhara region were positively associated with AMA. Conversely, factors including lower education level (no or primary education), contraceptive use, media access, rural residence adherence to postnatal check-ups and residing in the Afar region were negatively associated with AMA. All community-level factors were significantly associated with the outcome.
