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

purposeInterventional radiologists are among the healthcare professionals most exposed to ionizing scatter radiation. A 0.5 mm lead equivalent X-ray protective drape (MXPD, Mavig, Germany) was introduced to reduce operator radiation dose and has demonstrated efficacy during cardiac interventions. This study evaluates the efficacy of the MXPD during transfemoral liver interventions. MATERIALS &

methodsA single-center randomized controlled study was conducted to compare operator radiation exposure during transfemoral liver interventions (n = 100) with and without the MXPD. Primary outcome was the ratio of the combined operator radiation dose values-measured at the chest, eyes and both hands and normalized to the respective dose area products - between MXPD and control groups. Secondary outcomes included the ratios in operator radiation doses measured for the individual dosimeter locations.

resultsThe MXPD group showed a significantly lower normalized radiation dose per DAP (mean reduction 0.31 µSv; 95% CI 0.083-0.536, p = 0.009), representing a 43% reduction. The effect of the drape was the highest for the whole-body dose measured above the lead apron (55% reduction, p = 0.10), the left hand finger dose (43%, p = 0.20) and the eye lens dose estimated at the left temple (63%, p = 0.10) and in between the eyes (47%, p = 0.10).

conclusionThe MXPD can effectively reduce operator radiation dose during transfemoral arterial liver interventions, offering a practical adjunct to standard protective measures. LEVEL OF EVIDENCE: Level 1b, Randomized Controlled Trial.
