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
Continuous positive airway pressure (CPAP) is a primary non-invasive mode of respiratory support for preterm infants. However, emerging evidence suggests CPAP could be an underlying contributor to the unintended pathophysiology of wheezing and associated airway hyperreactivity (AHR) in former preterm infants. The therapeutic benefits of mesenchymal stem cells (MSCs) have been demonstrated in a variety of animal models and several clinical trials are currently underway to assess their safety profiles in the setting of prematurity and bronchopulmonary dysplasia (BPD). In the present study, using a mouse model of neonatal CPAP, we investigated whether conditioned medium harvested from cultures of human bone-marrow derived mesenchymal stem cells (hMSC) could rescue the CPAP-induced AHR, based upon previous observations of their anti-AHR properties. Newborn mice (male and female) were fitted with a custom-made mask for delivery of daily CPAP 3 h/day for the first 7 postnatal days. At postnatal day 21 (two weeks after CPAP ended), lungs were removed, precision-cut lung slices were sectioned and incubated for 48 h in vitro in conditioned medium collected from cultures of three different hMSC donors. As expected, CPAP resulted in AHR to methacholine compared to untreated control mice. hMSC conditioned medium from the cultures of all three donors completely reversed AHR. These data reveal potential therapeutic benefits of hMSC therapy, which may be capable of rescuing the long-term adverse effects of neonatal CPAP on human airway function.
