Inter-rater and intra-rater reliability of quantitative ultrasound in preterm infants: an observational cohort study.
Article in JBMR plus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Extremely premature infants are at high risk of metabolic bone disease of prematurity. Current diagnostic tools require radiation exposure, additional risks to patients, and likely provide late diagnosis. Serum markers of minerals are the current standard of care, but there are no universal diagnostic definitions. QUS is a potential diagnostic method that is non-invasive, provides immediate results, can be performed in the incubator, and has no radiation exposure. QUS has been studied in preterm infants, but few studies have evaluated the intra-rater and inter-rater reliability of QUS in preterm infants. Our study evaluated the inter-rater and intra-rater reliability in infants less than 28 wk or <1000 g at birth at a single level IV academic center. Three operators performed QUS on the tibia in infants with 3 separate measurements per operator at one month post birth (
