Fetal lung development via quantitative biomarkers from diffusion MRI and histological validation in rhesus macaques.

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
objectiveTo demonstrate sensitivity of diffusion-weighted MRI (DW-MRI) to pulmonary cellular-space changes during normal in utero development using fetal rhesus macaques, compared to histological biomarkers. STUDY
designIn vivo/ex vivo DW-MRI was acquired in 26 fetal rhesus lungs (early-canalicular through saccular stages). Apparent diffusion coefficients (ADC) from MRI and tissue area density (H&E), alveolar type-II cells (ABCA3), and epithelial cells (TTF1) from histology were compared between gestational stages.
resultsIn vivo/ex vivo ADC correlated with each other (Spearman ρ = 0.47, P = 0.038; Bland-Altman bias = 0.0835) and with area-density (in vivo ρ = -0.56, P = 0.011; ex vivo ρ = -0.83, P < 0.0001). In vivo/ex vivo ADC increased exponentially toward saturation with gestational stage (R
conclusionsFetal DW-MRI provides a non-invasive biomarker for pulmonary structural maturation, with a strong correlation to histological markers during tissue development in rhesus macaques. This method has strong potential for assessing human fetal development, particularly in patients with pulmonary hypoplasia.
