Gonad irradiation from fluoroscopy during upper limb orthopaedic procedures in a UK District General Hospital.

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
objectivesTo perform a dose assessment of radiation received to the surgeon's gonads when performing upper limb fluoroscopy-guided procedures when the C-arm may be positioned in between the surgeon's legs.
methodsA calibrated MDH-Radcal 2025 electrometer was used to read the radiation dose for a single exposure and a 5-s screening radiograph with the C-arm firing up and down. These were performed with and without a lead gown positioned over the ionisation chamber where it would ordinarily lie over gonads during surgery.
resultsWith the tube firing down and lead apron in place the single exposure (SE) recorded<0.01 uSv and screening exposure (SC) recorded 0.01 uSv. With the tube firing up, with lead the SE recorded 0.09 uSv and the SC 0.54 uSv. In the same situation without lead, the recordings were 0.13 uSv SE and 0. 65 uSv SC.
conclusionsWith the X-ray tube firing up, there is a measurable radiation dose to the area where the surgeons' gonads lie. The standard lead apron does not provide shielding of the gonads for a surgeon sitting down performing the operation with the tube firing up since the principal source of the radiation is below the edge of the apron and thus scatters up into the unprotected groin. ADVANCES IN KNOWLEDGE: Fluoroscopy with conventional C-arm in upper limb procedures can cause scatter irradiation to gonads. The X-ray beam should always be fired from top to bottom otherwise large doses can be emitted and the lead gown is less protective.
