[Evaluation of endoscopic visualisation for identifying premalignant gastric lesions in a Columbian population using histopathology as a reference].
Article in Atencion primaria, 2009. 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
aimTo evaluate the performance of endoscopic visualization in the identification of premalignant gastric lesions, with histopathological examination of biopsy samples as a reference test, in Bucaramanga, Colombia. LOCATION: League for the Fight Against Cancer, Bucaramanga, Colombia.
designDiagnostic technology evaluation with cross-sectional sampling. MEASUREMENTS: We calculate the sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio (+), likelihood ratio (-), kappa index and the prevalence rate kappa.
resultsA total of 155 patients were studied, with a mean age of 45.43 (14.15) years and an approximate male:female ratio of 2:1. The endoscopic visualization had a sensitivity of 87.84%, a specificity of 55.56%, a positive predictive value of 64.36%, a negative predictive value of 83.33%, a likelihood ratio+of 1.98, a likelihood ratio-de 0.22 and a kappa index of 0.4272, in the identification of preneoplastic lesions of the stomach in a population with a disease prevalence of 47.74%.
conclusionsThe endoscopic visualization of the gastrointestinal mucosa, allows a moderate and fast identification of early preneoplastic lesions, providing an opportunity of its early histopathological diagnosis.
