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

purposeTo evaluate factors related to conversion to open repair (OR) during thoracoscopic repair (TR) in congenital diaphragmatic hernia (CDH).

methodsCDH subjects who were diagnosed prenatally or within 6 h of birth and underwent TR at our institution from 2007 to 2015 were reviewed. Two groups were defined: Group A, subjects who tolerated TR; and Group B, subjects who required conversion to OR.

resultsTwenty-nine subjects (Group A, 20; Group B, 9) underwent TR. Patients' demographics were not significantly different between the two groups. In Group A, pre-operative arterial blood gas analysis showed mean PaCO2 37.4 mmHg, mean pH 7.45, and mean PaO2 201.6 mmHg, which were not significantly different from those of Group B (PaCO2 40.6 mmHg, pH 7.43, and PaO2 251.1 mmHg). Two Group B cases required conversion due to cardiopulmonary instability. The remaining seven cases were converted for technical reasons (large defect in two, anterior location of the defect in two, bleeding from short gastric vessels or spleen in two, and insufficient operative view in one).

conclusionsTR can be performed safely in selected cases of CDH. CDH with a large defect and/or an unusual location of the defect remains a challenge for pediatric surgeons.
