Dietary conjugated α-linolenic acid did not improve glucose tolerance in a neonatal pig model.

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
purposeThere is an increased interest in the benefits of conjugated α-linolenic acid (CLNA) on obesity-related complications such as insulin resistance and diabetes. The aim of the study was to investigate whether a 1% dietary supplementation of mono-CLNA isomers (c9-t11-c15-18:3 + c9-t13-c15-18:3) improved glucose and lipid metabolism in neonatal pigs.
methodsSince mono-CLNA isomers combine one conjugated two-double-bond system with an n-3 polyunsaturated fatty acid (PUFA) structure, the experimental protocol was designed to isolate the dietary structural characteristics of the molecules by comparing a CLNA diet with three other dietary fats: (1) conjugated linoleic acid (c9-t11-18:2 + t10-c12-18:2; CLA), (2) non-conjugated n-3 PUFA, and (3) n-6 PUFA. Thirty-two piglets weaned at 3 weeks of age were distributed among the four dietary groups. Diets were isoenergetic and food intake was controlled by a gastric tube. After 2 weeks of supplementation, gastro-enteral (OGTT) and parenteral (IVGTT) glucose tolerance tests were conducted.
resultsDietary supplementation with mono-CLNA did not modify body weight/fat or blood lipid profiles (p > 0.82 and p > 0.57, respectively) compared with other dietary groups. Plasma glucose, insulin, and C-peptide responses to OGTT and IVGTT in the CLNA group were not different from the three other dietary groups (p > 0.18 and p > 0.15, respectively). Compared to the non-conjugated n-3 PUFA diet, CLNA-fed animals had decreased liver composition in three n-3 fatty acids (18:3n-3; 20:3n-3; 22:5n-3; p < 0.001).
conclusionsThese results suggest that providing 1% mono-CLNA is not effective in improving insulin sensitivity in neonatal pigs.
