Transanal endoscopic microsurgery with 3-D (TEM) or high-definition 2-D transanal endoscopic operation (TEO) for rectal tumors. A prospective, randomized clinical trial.
Trial report in International journal of colorectal disease, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
purposeTransanal endoscopic microsurgery (TEM) is a three-dimensional viewing endoscopic system procedure which provides access to rectal tumors through a rectoscope. Two-dimensional transanal endoscopic operation (TEO), with the introduction of high-definition vision, achieves results that are comparable to those of the classical TEM. The main aim of the study was to compare the effectiveness of TEO and TEM systems in a prospective, randomized clinical trial.
methodSTUDY POPULATION: patients meeting inclusion criteria for diagnosis of rectal tumors with curative intent. Sample size, 36 patients. Patients were randomized to receive one of the two procedures. Study variables recorded were the following: preoperative data (time taken to assemble equipment, surgical time, quality of pneumorectum), postoperative morbidity and mortality, pathology study of the tumors, and economic analysis.
resultsThirty-six patients were analyzed according to intention to treat. Two patients were excluded. The final per-protocol analysis was 34 patients. There were no significant differences in the preoperative or operative variables, quality of pneumorectum, postoperative variables, or pathology results. A trend toward benefit was observed in favor of TEO in time required for assembly, surgical suture time, and total surgical time though the differences were not statistically significant. Statistically significant differences were found in terms of the total cost of the procedure, with mean costs of 2,031 <euro> ± 440 for TEO and 2,603 <euro> ± 507 for TEM (95% CI 218.15-926.486 <euro>, p = 0.003).
conclusionNo technical or clinical differences were observed between the results obtained with the two systems except lower cost with TEO.
