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

Pulmonary hemodynamics are necessary to measure for lifelong surveillance of cardiovascular function in children with tetralogy of Fallot (TOF). To measure cardiac index, invasive cardiac catheterization using the Fick principle or phase-contrast MRI (PC-MRI) can be used. However, estimates of oxygen consumption and other assumptions used in the Fick method may lead to significant inaccuracy, which are further exacerbated by disease characteristics such as pulmonary regurgitation. By comparison, PC-MRI can directly measure blood flow and regurgitant fraction. To investigate the potential complications of using the Fick principle, flow hemodynamics in 33 repaired TOF patients (7.6 ± 3.9 years) were investigated in patients who underwent cardiac catheterization and cardiac MRI. Pulmonary blood flow (Q
