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
The effects of extruded flaxseed-pulse mixture (LinPRO-24) on growth performance, tissue fatty acid composition, carcass traits, and meat quality in broilers were investigated. A total of 540-day-old male 308 Ross chicks were placed in pens (30 chicks/pen) and allocated to three diets (n = 6) in a completely randomized design. The diets were: CON (basal corn-soybean meal diet); LPA (CON+2.5% LinPRO-24); and LPB (CON+ 5.0% LinPRO-24). Diets were isocaloric and isonitrogenous, formulated for starter (day 1-10), grower (day 11-24), and finisher (day 24-34). Feed intake and body weight (BW) were recorded daily, and mortalities as they occurred to calculate average daily gain (AWG) and FCR. On day 34, visceral organs, breast tissue, and leg tissue were sampled. The CON group exhibited higher overall BW, AWG, and AFI than LPB (P < 0.05). Breast and leg tissues of birds fed LPB had the highest concentration of Alpha-linolenic acid (ALA) and total ω-3 PUFA followed by LPA; both had a higher ALA concentration than the CON group (P < 0.05). Thus, the ω-6:ω-3 ratio in these tissues was lower for LPA and LPB groups (P < 0.05). Additionally, both LPA and LPB groups had lower Docosatetraenoic acid (DTA, C22:4 ω-6), higher Docosapentaenoic acid (DPA, C22:5 ω-3) and total PUFA content, resulting in a reduced SFA:PUFA ratio in leg tissue compared with the CON group (P < 0.05). However, LPB negatively affected the water-holding capacity (WHC) in breast meat compared with the CON and in leg tissue compared with LPA treatment (P < 0.05). Moreover, LPB increased muscle hardness and gumminess in the breast compared with the CON group (P < 0.05), thereby negatively affecting meat textural qualities. Overall, both LPA and LPB diets increased the ω-3 PUFA content in poultry meat, thereby reducing the ω-6:ω-3 ratio. However, the current study suggests that the use of LinPRO-24 at 2.5% may be more appropriate for improving the fatty acid profile of broiler meat without compromising production performance and meat quality.
