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

To evaluate whether jugular venous NIRS (rSjvO₂) and baseline-calibrated cerebral NIRS (cal-rScO₂) can serve as surrogates for mixed venous oxygen saturation (SvO₂), and whether these inputs can support continuous cardiac output (CO) estimation during off-pump coronary artery bypass grafting (OPCAB). In this prospective observational study, 25 adults undergoing elective OPCAB were enrolled at a single tertiary center. NIRS sensors were placed over the left internal jugular vein (IJV) under ultrasound guidance and over the bilateral forehead. Pulmonary artery catheter measurements served as the reference for SvO₂ and thermodilution CO (CO
