1 · What the graph read from 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.

2 · The registry

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

This study evaluated the effects of 1,3-diacylglycerol (DAG) supplementation on the growth performance, nutrient digestibility, and physiological responses of broilers fed reduced-energy diets containing palm kernel meal (PKM). A total of 576 one-day-old mixed-sex Ross 308 broiler chicks were randomly allocated to four dietary treatments: positive control (PC), negative control (NC; PC - 100 kcal/kg ME and 5% PKM), T1 (NC + 0.05% 1,3-DAG), or T2 (NC + 0.10% 1,3-DAG). Broilers were fed the experimental diets for 35 d, and apparent total tract digestibility was determined during d 28-35 using chromium oxide as an indigestible marker. During the overall period (d 1-35), body weight gain and feed intake were not affected by dietary treatment (P > 0.05), whereas the feed conversion ratio (FCR) was significantly higher in the NC group than in the PC group (P < 0.001). Dietary 1,3-DAG supplementation linearly improved FCR (P < 0.001), and the FCR of the T2 group was comparable to that of the PC group. The apparent total tract digestibility of DM, nitrogen, energy, and fat was not affected by treatment (P > 0.05); however, significant linear increases in DM (P = 0.049), energy (P = 0.015), and fat digestibility (P < 0.001) were observed with increasing 1,3-DAG supplementation. Nutrient intake and retention were largely unaffected by treatment (P > 0.05), although fat intake was significantly higher in the NC group than in the PC group (P = 0.012). In contrast, nutrient excretion, particularly fat excretion, was significantly reduced by 1,3-DAG supplementation in a dose-dependent manner (P < 0.001). Serum lipid profiles and rectal temperature were not influenced by dietary treatment (P > 0.05). In conclusion, dietary 1,3-DAG supplementation improved FCR in broilers fed PKM-based reduced-energy diets by enhancing nutrient utilization, particularly fat digestibility, without affecting their physiological parameters.
