Do colorectal cancer resections improve diabetes in long-term survivors? A case-control study.
Observational study in Surgical endoscopy, 2014. 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
backgroundA clinical study was designed that aimed to analyze whether resection of the large bowel in cancer patients might benefit diabetes mellitus.
methodsThis prospective case-control study included retrospective information. Patients (n = 247) included diabetic and euglycemic groups with colorectal cancer operations (n = 60), cancer gastrectomy (n = 72), exclusive chemoradiotherapy for rectal cancer (n = 46), and noncancer clinical controls (n = 69). Follow-up periods were, respectively, 79.2 ± 27.4, 86.8 ± 25.1, 70.0 ± 26.3, and 85.1 ± 18.2 months (NS). Diabetes groups included patients with prediabetes.
resultsDiabetes remission, defined as conversion from diabetes to prediabetes or from this condition to normal, was documented in, respectively, 32.4 % (11 of 34), 41.2 % (14 of 34), 7.1 % (1 of 14), and 7.7 % (3 of 39) in the four cohorts (P = 0.004). Within the same period, progression of euglycemic participants to diabetes occurred in 30.8 % (8 of 26), 63.2 % (24 of 38), 25.0 (8 of 32), and 20.0 % (6 of 30) (P = 0.028). Diabetes amelioration was associated with weight loss in gastrectomy patients but not in the other groups. Dietary intake, estimated in the two surgical populations, did not predict outcome.
conclusionsDiabetes amelioration after colorectal interventions was demonstrated, but progression of euglycemic patients toward prediabetes was not changed in comparison with nonsurgical controls. It is speculated that reshaping of the bowel microbiome or hormone changes after colorectal interventions underlay the improvement in diabetes. Body weight fluctuations could not be incriminated in this investigation.
