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

Precise temperature monitoring is important for thermal therapy, vascular physiology, and brain function research. Photoacoustic thermometry often relies on hemoglobin-related wavelengths and is easily affected by hemoglobin concentration, oxygenation, and optical fluence. Here, we propose and validate a water-sensitive photoacoustic thermometry strategy at 960 nm in cerebrovascular phantom configurations containing a straight human whole-blood channel, with and without a bone-like shell. CT-guided registration enabled structurally constrained ROI analysis. Although frame-by-frame PAI signals fluctuated, clear temperature-dependent trends were preserved and strengthened by statistical aggregation. In the phantom without the bone-like shell, 0.1°C temperature-binned median aggregation yielded an apparent calibration R
