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

introductionBetween 2005 and 2010, reductions in newborn mortality fell behind those for maternal and under-five child mortality in Cambodia. To improve newborn outcomes, we developed and scaled-up early essential newborn care (EENC) nationally using a new clinical coaching and data-based quality improvement approach. This study aimed to determine EENC's contribution to Cambodia's observed neonatal mortality decline between 2010 and 2022.

methodsStandard indicators in the EENC monitoring and evaluation framework were calculated from programme records, nationally representative population-based surveys and facility-based assessments using standardised methods. The Lives Saved Tool (LiST) was used to model newborn lives saved 2010-2022 using facility estimates of care quality.

resultsNewborn mortality declined from 27 to 8/1000 live births (70.4%) comparing 2010 and 2022. The average annual rate of newborn mortality decline accelerated by 33% after EENC introduction in 2012 compared with the previous 10 years, with greatest declines among high-risk groups (poorest, rural, uneducated and with low birth interval). Between 2010 and 2022, EENC was integrated into national and subnational policies, standards and implementation plans and introduced to 87.6% of birth facilities. The average birth practice score rose to 72.9% (95% CI 59.0% to 83.4%) in 2022, from 6% (95% CI 1.7% to 20.1%) in 2011. Significant improvements were seen in application of clean birth environments, immediate drying and stimulation, thermal protection (immediate and prolonged skin to skin contact), delayed cord clamping and clean cord care. LiST modelling estimated that EENC interventions averted 21 704 Cambodian newborn deaths (range 17 694-26 450) during 2010-2022 and were responsible for 75.3% (range 69.5%-80.5%) of the observed national mortality reduction.

conclusionA new approach to EENC programme implementation led to sustained country-wide improvements in evidence-based practices around birth. Improved care quality was associated with 69.5-80.5% of the observed neonatal mortality decline in Cambodia between 2010 and 2022.
