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 evaluate a structured basic radiology course for Family Medicine residents delivered in a 3-dimensional (3D) virtual environment (Second Life). We hypothesized that participation would be associated with higher post-course knowledge test scores and high learner satisfaction.
methodsA quasi-experimental multi-cohort pretest-posttest study was conducted across 3 consecutive cohorts of Family Medicine residents in Spain in 2019. Ninety-six participants engaged in a 15-day course combining synchronous and asynchronous activities. Sixty-five participants provided paired pre- and post-intervention knowledge assessments, which were analyzed using paired t-tests. Learner satisfaction was evaluated using a structured questionnaire with Likert-scale items, numerical ratings (0-10), and open-ended responses. Pre- and post-test scores and ratings were compared using paired t-tests, and Mann-Whitney U tests were used for Likert-scale data. Qualitative data from open-ended responses were analyzed using thematic coding.
resultsParticipants had significantly higher post-course knowledge test scores, increasing from 47.4±11.6 to 58.2±11.9 (mean difference, 10.8; P<0.001; paired-sample Cohen's d [dz]=0.67). High agreement was observed across most satisfaction items, with median scores ranging from 4 to 5. Content relevance, usefulness for clinical practice, and instructor performance received the highest ratings. Lower scores were observed for peer interaction and platform usability.
conclusionA structured radiology course delivered in a 3D virtual environment was associated with higher immediate post-course knowledge test scores and high learner satisfaction among Family Medicine residents. The findings support the feasibility of repeated course delivery, although controlled studies are warranted.
