Probe-based confocal laser endomicroscopy for evaluating the submucosal invasion of colorectal neoplasms.
Article in Surgical endoscopy, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
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
backgroundProbe-based confocal laser endomicroscopy (pCLE) is a novel method for in vivo histological analysis of colorectal neoplasm mucosa, which provides meaningful information for the development of adequate therapeutic strategies. However, the in vivo histology of colorectal neoplasm submucosa has not been studied. We assessed the feasibility and safety of pCLE for evaluating colorectal submucosa, and identified and validated diagnostic criteria for submucosal carcinoma infiltration.
methodsFrom March to July 2014, 83 pCLE videos of 51 lesions in 31 patients who underwent scheduled colonoscopic procedures for the removal of colorectal neoplasms were acquired consecutively. During the procedures, pCLE videos of the lesions and biopsy samples for histopathological analysis were acquired. Final histopathological results were used as the gold standard.
resultsBased on the confocal pattern, we classified colorectal submucosa findings as negative (superficial submucosa, deep submucosa, and submucosa with fibrosis) or indicative of carcinoma infiltration. Dark and irregular cell nests with irregular cell architecture and little or no mucin were seen in submucosal carcinoma infiltration. Based on rates of correlation with pathological findings, the sensitivity, specificity, and accuracy of the classification of submucosal carcinoma infiltration by two observers were 91.7, 86.8, and 88.0 %, respectively. In addition, the results showed good interobserver agreement for the detection of submucosal carcinoma infiltration (κ = 0.757, standard error = 0.102). No adverse events occurred during the procedures.
conclusionsSubmucosa assessment by pCLE is feasible and safe. pCLE is useful for the differentiation of normal submucosa from carcinoma infiltration, particularly when infiltration is accompanied by severe fibrosis. Large-scale prospective studies are needed to further evaluate the clinical impact of the use of pCLE during endoscopy.
