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

Digital variance angiography (DVA) exhibits promising prospects with respect to radiation exposure in digital subtraction angiography (DSA). This study aimed to determine the reduction of radiation dose in endovascular peripheral interventions (EPI) using DVA. The DVA imaging tool v6.0 (Kinepict Medical Imaging Tool, version 6.0.4, Kinepict Health Ltd., Budapest, Hungary) was utilized for patients undergoing EPI using digital angiography. EPI normal dose (EPI-ND) protocols were adapted from 1.20 to 0.81 µGy/frame to EPI low dose (EPI-LD) protocols using DVA-LD acquisitions with 0.36 µGy/frame and occasionally 0.24 µGy/frame based on specific examination requirements. The dose area product (DAP) was evaluated and contrast-to-noise ratio (CNR) was measured for each DSA acquisition. Evaluation included 370 EPI-ND and 62 EPI-LD using DVA-LD of three lower extremity regions (mean age: 73 ± 11 years, 67% male). LD protocols decreased median DAP of ND protocols significantly by 62.0% in pelvic, 53.8% in femoral and popliteal, and 59.4% in cruro-pedal regions, respectively (p < .005). DVA-LD increased median CNR significantly compared to DSA-LD (p < .001), and was equal to DSA-ND (p > .15). Image quality was enhanced by CNR
