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
purposeThis study aimed to determine whether the C-arm’s lowest possible radiation (LPR) setting could lower the total radiation exposure compared to the standard method, while maintaining sufficient image quality. The LPR options are quarter-dose mode (low-dose versus standard dose) and pulsed images (four images per second versus 24 images/sec).
methodsA retrospective study of patient records between 05/2023 and 08/2024 was undertaken to retrieve information on imaging and type of surgery. The cumulative radiation dose (CD, in milliGray) and exposure duration (d, in seconds) were retrieved from the report automatically generated by the fluoroscopy machine. The relative radiation dose (RD = CD/d, in mGy/sec) was calculated to compare results across different groups, which included four anatomical regions: distal lower limb (dLL) - tibia, ankle, and foot; proximal lower limb (pLL) - hip, femur, and patella; distal upper limb (dUL) - forearm and wrist; proximal upper limb (pUL) - shoulder and humerus.
resultsFour-hundred-thirty-two cases were reviewed, 193 in LPR and 239 in standard dose. The four groups included: 226 dLL, 100 pLL, 56 dUL and 50 pUL. Overall RD decreased by 48%. Reductions by anatomical region were 76% (pUL), 64% (dUL), 75% (pLL), and 58% (dLL). There was no overall increase in total exposure duration with LPR mode (no increase in images taken).
conclusionUsing the C-arm’s LPR settings for orthopedic surgery in a retrospective, two-surgeon design allows a significantly lower RD exposure of 48% for operating room personnel, with sufficient image quality not to impact the number of images required. LEVEL OF EVIDENCE: Level III.
