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

Congenital absence or deficiency of tracheal rings is exceptionally rare and may cause diffuse tracheobronchomalacia (TBM) with life-threatening airway collapse. A 6-month-old girl had persistent stridor from birth, cyanotic spells during feeding, and nocturnal desaturation. Cervicothoracic CT suggested severe airway collapse, and rigid bronchoscopy showed a flattened trachea and main bronchi without visible cartilaginous rings, consistent with ring agenesis and diffuse TBM. Curative surgery was not feasible. After in-hospital titration during a nap, face-mask CPAP with heated humidification was prescribed during sleep and postprandial windows. A minimal effective pressure of 6 cmH
