Fewer spontaneous arousals in infants with apparent life-threatening event.
Article in Sleep, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
STUDY
objectivesA deficit in arousal process has been implicated as a mechanism of sudden infant death syndrome (SIDS). Compared with control infants, SIDS victims showed significantly more subcortical activations and fewer cortical arousals than matched control infants. Apparent life-threatening event (ALTE) is often considered as an aborted SIDS event. The aim of this study was to study the arousal characteristics of ALTE infants during the first months of life.
design35 ALTE infants were studied with nighttime polysomnography at 2-3, 5-6, and 8-9 months of age. Eighteen of the infants had mothers who smoked. The infants were born full term and were usually supine sleepers. Sleep state and cardiorespiratory parameters were scored according to recommended criteria. Arousals were differentiated into subcortical activations or cortical arousals, according to the presence of autonomic and/or electroencephalographic changes. The results were compared with those of 19 healthy infants with nonsmoking mothers.
resultsDuring NREM sleep, the ALTE infants had fewer total arousals, cortical arousals, and subcortical activations at 2-3 and 5-6 months (P < 0.001) than control infants. ALTE infants with smoking mothers had more obstructive apnea (P = 0.009) and more subcortical activations during REM sleep at 2-3 months of age (P < 0.001) than ALTE infants with nonsmoking mothers.
conclusionsSpontaneous arousals were differently altered in ALTE infants than in SIDS infants, suggesting an entity different from SIDS. ALTE infants with smoking mothers had arousal and respiratory characteristics that were similar to future SIDS victims, suggesting some common abnormalities in brainstem dysfunction.
