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

objectivesIncreasing access to skilled birth attendance, usually via childbirth in health facilities, is a key intervention to reduce maternal and perinatal mortality and morbidity. Yet, in some countries of sub-Saharan Africa, the uptake is <50%. Age and parity are determinants of facility-based delivery, but are strongly correlated in high fertility settings. This analysis assessed the independent effect of age on facility-based delivery by restricting to first-order births. It was hypothesised that older first-time mothers in this setting might have lower uptake of facility-based deliveries than women in the most common age groups for first birth.

settingThe most recent Demographic and Health Surveys from 34 sub-Saharan African countries were used to assess women's delivery locations.

participants72 772 women having their first birth in the 5 years preceding the surveys were included in the analysis. PRIMARY AND SECONDARY OUTCOME MEASURES: Proportions and 95% CIs of facility-based deliveries were estimated overall and by country. Multivariable logistic regression was used to calculate the odds of facility-based delivery for different maternal age groups (15-19, 20-24 and ≥25 years) for a pooled sample of all countries.

results59.9% of women had a facility-based delivery for their first birth (95% CI 58.6 to 61.2), ranging from 19.4% in Chad to 96.6% in Rwanda. Compared with women aged 15-19 years, the adjusted odds of having a facility-based delivery for those aged 20-24 was 1.4 (95% CI 1.3 to 1.5, p<0.001) and for those aged ≥25, 1.9 (95% CI 1.6 to 2.2, p<0.001).

conclusionsOlder age at first birth was independently associated with significantly higher odds of facility-based delivery. This went against the hypothesis. Further mixed-method research is needed to explore how increased age improves uptake of facility-based delivery. Promoting facility-based delivery, while ensuring quality of care, should be prioritised to improve birth outcomes in sub-Saharan Africa.
