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

objectiveThe aim of this study is to determine the frequency of neural tube defects (NTDs) and to examine the epidemiological characteristics of NTD related deaths in Turkey.

methodsThis nationwide descriptive study was included NTD related infant deaths, termination of pregnancy for fetal anomaly (ToPFA) and stillbirth cases registered in Death Notification System between 2014 and 2019, and patients diagnosed with NTD in the 2018 birth cohort.

findingsIn the 2018 birth cohort, there were 3475 cases of NTD at birth (27.5 per 10,000). The fatality rates for live-born babies with NTD in this cohort were 13.5% at first year, and 15.6% at the end of March, 2022. NTDs were associated with 11.7% of ToPFA cases, 2.5% of stillbirths and 2.8% of infant deaths in 2014-2019. NTD related stillbirth rate was 1.74 per 10,000 births, while NTD related ToPFA rate and infant mortality rate were 0.61 and 2.70 per 10,000 live births respectively. NTD-related stillbirth and infant mortality rate were highest in the Eastern region (3.64 per 10,000 births; 4.65 per 10,000 live births respectively), while ToPFA rate was highest in the North and West regions (1.17 and 0.79 per 10,000 live births respectively) (p < 0.05). Prematurity and low birth weight were the variables with the highest NTD related rates for stillbirths (11.26 and 16.80 per 10,000 birth), ToPFA (9.25 and 12.74) per 10,000 live birth), and infant deaths (13.91 and 20.11 per 10,000 live birth) (p < 0.05).

conclusionNTDs are common and have an important place among the mortality causes in Turkey. Primary prevention through mandatory folic acid fortification should be considered both to reduce the frequency of NTD and related mortality rates.
