Mammographic interpretation: radiologists' ability to accurately estimate their performance and compare it with that of their peers.
Article in AJR. American journal of roentgenology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThe purposes of this study were to determine whether U.S. radiologists accurately estimate their own interpretive performance of screening mammography and to assess how they compare their performance with that of their peers. SUBJECTS AND
methodsBetween 2005 and 2006, 174 radiologists from six Breast Cancer Surveillance Consortium registries completed a mailed survey. The radiologists' estimated and actual recall, false-positive, and cancer detection rates and positive predictive value of biopsy recommendation (PPV(2)) for screening mammography were compared. Radiologists' ratings of their performance as lower than, similar to, or higher than that of their peers were compared with their actual performance. Associations with radiologist characteristics were estimated with weighted generalized linear models.
resultsAlthough most radiologists accurately estimated their cancer detection and recall rates (74% and 78% of radiologists), fewer accurately estimated their false-positive rate (19%) and PPV(2) (26%). Radiologists reported having recall rates similar to (43%) or lower than (31%) and false-positive rates similar to (52%) or lower than (33%) those of their peers and similar (72%) or higher (23%) cancer detection rates and similar (72%) or higher (38%) PPV(2). Estimation accuracy did not differ by radiologist characteristics except that radiologists who interpreted 1000 or fewer mammograms annually were less accurate at estimating their recall rates.
conclusionRadiologists perceive their performance to be better than it actually is and at least as good as that of their peers. Radiologists have particular difficulty estimating their false-positive rates and PPV(2).
