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
purposeThe knowledge of sleep disorders in children with brain tumours is limited. We aim to investigate the presence of possible sleep disturbances in this population.
methodsPolysomnography (PSG) analysis was performed in our Paediatric Clinic from October 2017 to March 2019. Patients between 2 and 16 years old, treated for brain tumours at least 6 months after the end of treatments, were included. The exclusion criteria were children with seizures, taking sleep-interfering therapies, and adenotonsillar hypertrophy. We performed overnight PSG according to the American Academy of Sleep Medicine guidelines.
resultsWe enrolled 16 patients (11 male). The median age at the diagnosis was 9.3 years (IQR 25-75°, 3.5-11.5), and the median age at PSG exam was 12.5 years (IQR 25-75°, 6.9-15.3). Eight out of sixteen patients had infratentorial tumours. The mean sleep record duration was 514 min (SD ± 86 min). The mean oxygen saturation was 97%, and the mean heart rate was 71 bpm (SD ± 14). Respiratory records showed a significantly increased median central apnoea index (CAI) in the infratentorial group (median value 1.2, IQR 25-75°, 0.85-1.45) compared with the supratentorial group (median value 0.3; IQR 25-75°, 0.2-0.5; p 0.0156). Electroencephalogram records showed alterations of night sleep organization: in particular, an increased N1 period, a shorter N2 period, and higher delta-sleep activity N3 period, compared with healthy populations.
conclusionOur results highlighted a higher prevalence of central apnoea in children with infratentorial tumours, showing a possible impact of posterior fossa localization on sleep and ventilatory control. Moreover, we described several sleep structure alterations, identifying an important issue to be taken into account in the follow-up of patients with brain tumours.
