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

backgroundAnti-scatter grids are commonly used for cardiac catheterization in children with heart disease. However, the effect of the grid on the radiation dose or image quality has not been sufficiently demonstrated.

objectiveTo investigate the effect of the removal of an anti-scatter grid on radiation dose and image quality in phantom and clinical settings. MATERIALS AND

methodsThis research consists of a preliminary study using a manufactured phantom simulating a newborn's chest thickness and a clinical study of 30 infants with simple congenital heart disease. We evaluated the exposure dose by dose area product (DAP), air kerma (AK), and image quality using visual and physical assessments.

resultsIn the phantom study, removal of the anti-scatter grid decreased DAP and AK by 25.0% to 55.6%. In the clinical study, the DAP (sum) and AK (sum) without an anti-scatter grid were significantly lower than with the grid (1.22±0.58 Gy·cm

conclusionsThe removal of the anti-scatter grid did not affect the accuracy of the examination and achieved a lower radiation dose in both phantom and clinical studies. Cardiac catheterization without an anti-scatter grid may be a beneficial option for small patients with simple congenital heart disease.
