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

backgroundUnsedated MRI use in pediatric clinical and research settings is often feasible, but advanced imaging techniques like cerebrovascular reactivity (CVR) may affect tolerability of unsedated MRIs. Exogenous carbon dioxide (CO

objectiveWe hypothesized that children would tolerate MRI with exogenous CO MATERIALS AND

methodsChildren with and without sickle cell disease and/or reactive airway disease participated in prospective, single-site unsedated MRI observational studies and completed a post-scan questionnaire. A RespirAct® device delivered CO

resultsOne-hundred children participated, with a median age of 14.0 years [11.0, 16.3]. Sickle cell disease and/or reactive airway disease was present in 35% (35/100) and 16% (16/100), respectively. CVR sessions occurred in 75 participants, while 25 had MRI only. All children tolerated and completed the scans; 77% (58/75) had usable CVR data. Motion was similar between those with and without CVR (P=0.33). Children undergoing CVR were more likely to report symptoms, mainly shortness of breath (42/75 vs 3/25; P<0.001), compared to MRI only. Eleven children reported mild, temporary symptoms post-CVR scan; all resolved within a few hours. No serious adverse events occurred. Three children (CVR group) reported unwillingness to repeat the scan.

conclusionChildren tolerate MRI with exogenous CO
