The impact of experience on radiology report uncertainty for early-career musculoskeletal radiologists.
Article in Skeletal radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo quantify how experience influences uncertainty in musculoskeletal (MSK) magnetic resonance imaging (MRI) reports produced by early-career radiologists. MATERIALS AND
methodsIn this retrospective single-center study, we reviewed all MRI reports dictated during the first 5 years of practice (2014-2024) by 10 musculoskeletal radiologists, yielding 56,534 reports. Uncertainty of reports was measured with the following variables: uncertain word percentage, uncertain report percentage (reports containing ≥ 1 uncertain term), follow-up report percentage (reports containing ≥ 1 follow-up term), and word count. A rule-based natural language-processing pipeline parsed Impression sections for this data. For each report, we calculated uncertain word percentage and binary indicators for uncertain reports and follow-up requests. Multivariable logistic regression, with radiologist identity and experience as predictors, modeled the odds of uncertain wording, uncertain reports, and follow-up recommendations, using radiologist-clustered standard errors; linear regression assessed the effect of experience on word count.
resultsEach additional year of experience was associated, after adjustment for radiologist identity, with lower odds of uncertainty-related wording (OR = 0.88, 95% CI = 0.85-0.91, p < 0.001), uncertain reports (OR = 0.87, 95% CI = 0.77-0.98, p = 0.02), and follow-up recommendations (OR = 0.84, 95% CI = 0.75-0.93, p = 0.001). Follow-up recommendations decreased by 41.8% over 5 years. Word count showed no evidence of a difference. Inherent individual radiologist characteristics also affected these variables.
conclusionMusculoskeletal MRI report uncertainty decreased with radiologist experience and was also influenced variably by inherent characteristics of radiologists.
