Flip Angle Errors in Actual Flip Angle Imaging Using Polyvinylpyrrolidone/Water-Based Phantoms.
Article in Magnetic resonance in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
purposeThe aim of this work is to report and investigate unexpected errors in actual flip angle imaging (AFI) applied to phantom fillings based on polyvinylpyrrolidone (PVP).
methodsFlip angle maps of PVP/water mixtures with different PVP ratios were acquired at 3 T and 7 T using a 3D cartesian AFI. The influence of spoiling was investigated by varying the RF-spoiling phase increment Φ
resultsMeasurements reveal spoiling curves of PVP/water mixtures that lack the symmetry around Φ
conclusionUnder certain conditions, AFI of PVP/water mixtures suffers from errors originating from interferences of the water and PVP signal components. This can severely reduce the accuracy of the AFI and must be considered for
