Senior internal medicine residents' confidence with essential topics in evidence-based medicine taught during internship.
Article in Journal of graduate medical education, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundFew studies have examined residents' retained knowledge and confidence regarding essential evidence-based medicine (EBM) topics.
objectiveTo compare postgraduate year-3 (PGY-3) residents' confidence with EBM topics taught during internship with that of PGY-1 residents before and after exposure to an EBM curriculum.
methodsAll residents participated in an EBM curriculum during their intern year. We surveyed residents in 2009. PGY-1 residents completed a Likert-scale type survey (which included questions from the validated Berlin questionnaire and others, developed based on input from local EBM experts). We administered the Berlin questionnaire to a subset of PGY-3 residents.
resultsForty-five PGY-3 (88%; n = 51) and 42 PGY-1 (91%; n = 46) residents completed the survey. Compared with PGY-1 residents pre-curriculum, PGY-3 residents were significantly more confident in their knowledge of pre- and posttest probability (mean difference, 1.14; P = .002), number needed to harm (mean difference, 1.09; P = .002), likelihood ratio (mean difference, 1.01; P = .003), formulation of a focused clinical question (mean difference, 0.98; P = .001), and critical appraisal of therapy articles (mean difference, 0.91; P = .002). Perceived confidence was significantly lower for PGY-3 than post-curriculum PGY-1 residents on relative risk (mean difference, -0.86; P = .002), study design for prognosis questions (mean difference, -0.75; P = .004), number needed to harm (mean difference, -0.67; P = .01), ability to critically appraise systematic reviews (mean difference, -0.65, P = .009), and retrieval of evidence (mean difference, -0.56; P = .008), among others. There was no relationship between confidence with and actual knowledge of EBM topics.
conclusionsOur findings demonstrate lower confidence among PGY-3 than among PGY-1 internal medicine residents for several EBM topics. PGY-3 residents demonstrated poor knowledge of several core topics taught during internship. Longitudinal EBM curricula throughout residency 5 help reinforce residents' EBM knowledge and their confidence.
