Evaluating the potential utility of three-dimensional printed models in preoperative planning and patient consent in gastrointestinal cancer surgery.
Article in Annals of the Royal College of Surgeons of England, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionThe MATERIALS AND
methodsEthical approval was obtained. From a normal computed tomography scan, three-dimensional models of the stomach, pancreas and rectum were rendered and printed on an Ultimaker™ three-dimensional printer. Semi-structured interviews were performed with surgeons and patients to explore perceived model effectiveness and utility. Likert scales were used to grade responses (1 = strongly disagree; 10 = strongly agree) and qualitative responses recorded.
resultsA total of 26 surgeons (9 rectal, 9 oesophagogastric, 8 pancreatic) and 30 patients (median age 62 years, interquartile range, IQR, 68-72 years; 57% male) were recruited. Median surgeon scores were effectiveness for preoperative planning, 6 (IQR 3-7), authenticity, 5 (IQR 3-6), likability, 6 (IQR 4-7), promoting learning, 7 (IQR 5-8), utility, 6 (IQR 5-7) and helping patients, 7 (IQR 5-8). Median patient scores were usefulness to the surgeon, 8 (IQR 7-9), authenticity, 8 (IQR 6-8), likability, 8 (IQR 7-8), helping understanding of condition, 8 (IQR 8-9), helping understanding of surgery, 8 (IQR 7-9) and feeling uncomfortable, 1 (IQR 1-4). Median overall decisional conflict score (0 = no; 100 = high) was 22 (IQR 19-28) and decision effectiveness was 25 (IQR 19-30). DISCUSSION: Overall, patients and surgeons considered that three-dimensional printed models were effective and had potential utility in education and, to a lesser extent, preoperative planning. Patient decisional conflict and effectiveness scores were weighted towards certainty in decision making but had room for improvement, which three-dimensional models may help to facilitate.
