Conversions in laparoscopic surgery for rectal cancer.
Trial report in Surgical endoscopy, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
backgroundLaparoscopic surgery offers patients with rectal cancer short-term benefits and similar survival rates as open surgery. However, selecting patients who are suitable candidates for laparoscopic surgery is essential to prevent intra-operative conversion from laparoscopic to open surgery. Clinical and pathological variables were studied among patients who had converted laparoscopic surgeries within the COLOR II trial to improve patient selection for laparoscopic rectal cancer surgery.
methodsBetween January 20, 2004, and May 4, 2010, 1044 patients with rectal cancer enrolled in the COLOR II trial and were randomized to either laparoscopic or open surgery. Of 693 patients who had laparoscopic surgery, 114 (16 %) were converted to open surgery. Predictive factors were studied using multivariate analyses, and morbidity and mortality rates were determined.
resultsFactors correlating with conversion were as follows: age above 65 years (OR 1.9; 95 % CI 1.2-3.0: p = 0.003), BMI greater than 25 (OR 2.7; 95 % CI 1.7-4.3: p < 0.001), and tumor location more than 5 cm from the anal verge (OR 0.5; CI 0.3-0.9). Gender was not significantly related to conversion (p = 0.14). In the converted group, blood loss was greater (p < 0.001) and operating time was longer (p = 0.028) compared with the non-converted laparoscopies. Hospital stay did not differ (p = 0.06). Converted procedures were followed by more postoperative complications compared with laparoscopic or open surgery (p = 0.041 and p = 0.042, respectively). Mortality was similar in the laparoscopic and converted groups.
conclusionsAge above 65 years, BMI greater than 25, and tumor location between 5 and 15 cm from the anal verge were risk factors for conversion of laparoscopic to open surgery in patients with rectal cancer.
