Probe-based confocal laser microscopy identifies criteria predictive of active celiac sprue.
Trial report in Digestive diseases and sciences, 2012. 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
backgroundCeliac sprue is an underdiagnosed chronic intestinal inflammatory disease. Probe-based confocal laser microscopy (CLM) is a novel endoscopic technique for in vivo inspection of the intestinal mucosa that has not been evaluated in celiac sprue yet.
aimsTo develop CLM criteria most predictive of celiac pathology in a prospective pilot study.
methodsTwenty-one patients (male n = 5, f = 16, mean age 52 years) with established or suspected celiac sprue, seven of whom had confirmed active disease (Marsh III) and 14 duodenal normal mucosa. CLM images from 91 duodenal sites were assessed. CLM recordings were obtained next to Argon beamer labeled areas. Biopsies were taken from the same spots for precise histological matching. After establishing histology-correlated criteria on one sample per patient, the remaining CLM recordings from the same patients were randomized and blindly evaluated.
resultsVillous atrophy and irregular appearing villi were most predictive of celiac pathology. Although the presence of crypts was diagnostic for celiac pathology, it was only recognized in 26.7% of celiac pathology sites. Using these criteria in the blinded assessment, the overall endoscopist's prediction of celiac sprue was accurate in 89.8% of all biopsy sites in 85.7% of all patients. Preliminary interobserver agreement testing villous atrophy, irregular villi, and crypts was poor (kappa 0.05 to 0.26).
conclusionsProbe-based CLM criteria developed in this pilot trial appear promising for the detection of active celiac sprue. Preliminary interobserver variability was high, indicating a learning curve effect. Our criteria need validation in an independent patient population.
