Gestational age and 1-year hospital admission or mortality: a nation-wide population-based study.
Article in BMC pediatrics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
backgroundDescribe the 1-year hospitalization and in-hospital mortality rates, in infants born after 31 weeks of gestational age (GA).
methodsThis nation-wide population-based study used the French medico-administrative database to assess the following outcomes in singleton live-born infants (32-43 weeks) without congenital anomalies (year 2011): neonatal hospitalization (day of life 1 - 28), post-neonatal hospitalization (day of life 29 - 365), and 1-year in-hospital mortality rates. Marginal models and negative binomial regressions were used.
resultsThe study included 696,698 live-born babies. The neonatal hospitalization rate was 9.8%. Up to 40 weeks, the lower the GA, the higher the hospitalization rate and the greater the likelihood of requiring the highest level of neonatal care (both p < 0.001). The relative risk adjusted for sex and pregnancy-related diseases (aRR) reached 21.1 (95% confidence interval [CI]: 19.2-23.3) at 32 weeks. The post-neonatal hospitalization rate was 12.1%. The raw rates for post-neonatal hospitalization fell significantly from 32 - 40 and increased at 43 weeks and this persisted after adjustment (aRR = 3.6 [95% CI: 3.3-3.9] at 32 and 1.5 [95% CI: 1.1-1.9] at 43 compared to 40 weeks). The main causes of post-neonatal hospitalization were bronchiolitis (17.2%), gastroenteritis (10.4%) ENT diseases (5.4%) and accidents (6.2%). The in-hospital mortality rate was 0.85‰, with a significant decrease (p < 0.001) according to GA at birth (aRR = 3.8 [95% CI: 2.4-5.8] at 32 and 6.6 [95% CI: 2.1-20.9] at 43, compared to 40 weeks.
conclusionThere's a continuous change in outcome in hospitalized infants born above 31 weeks. Birth at 40 weeks gestation is associated with the lowest 1-year morbidity and mortality.
