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

The goal of this study was to assess radiation doses to the eyes of seated patients and medical staff during a videofluoroscopic swallowing study (VFSS), considering the effects of lead-equivalent glasses and the height of the medical staff. Entrance surface air kerma (ESAK) at eye level was measured using nanoDot dosimeters on anthropomorphic phantoms representing medical staff with heights of 150, 165, and 180 cm. ESAK measurements were performed with and without 0.5-0.6 mm lead-equivalent glasses. During a 10-minute fluoroscopy procedure, the mean ESAK at patient's eyes without lead-equivalent glasses was higher in the anteroposterior (AP) position (36.5 mGy) than in the lateral position (14.5 mGy). The corresponding ESAK at medical staff's eyes was notably higher in the 150-cm phantom (0.097 mGy), with an increase of 77.1% compared with that in the 165-cm phantom (0.043 mGy) and 87.4% compared with that in the 180-cm phantom (0.038 mGy). The radioprotective efficiency of lead-equivalent glasses in patients in the anteroposterior position was 92.0-93.4%, which was higher than that in the lateral position (15.8-83.2%). Radiation doses to the eyes were highest for shorter medical staff, highlighting the importance of protective measures, especially for those with shorter stature. The radioprotective efficiency of lead-equivalent glasses was found to be lower in the lateral position, underscoring the need for careful consideration of glasses design.
