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
objectiveAn experiment was conducted to test the hypothesis that inclusion of spray dried plasma (SDP) increases the apparent ileal digestibility (AID) of starch and the AID and standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) from other ingredients in diets for young pigs.
methodsThirty weanling barrows (body weight: 9.3±0.6 kg) with a T-cannula in the distal ileum were allotted to a triplicated 10×3 Youden square design with 10 diets and three periods of 7 d. Eight diets with ingredient combinations typically used in the U.S.A. (corn and soybean meal [SBM]), Canada (wheat, barley, SBM, and fermented SBM), the European Union (corn, SBM, wheat, and barley), and Asia (corn, SBM, ground rice, and fermented SBM) were formulated. Four diets contained no SDP, and four diets contained 6% SDP. A diet with SDP as the sole source of AA and a nitrogen-free diet were also included.
resultsAn interaction between region and SDP was observed for the AID and SID of CP and most AA. The SDP did not affect AID or SID of AA and CP in U.S.A. or Asian diets, but SDP increased (p<0.05) the AID of CP and the SID of Gly in the European Union diet. In the Canadian diet, SDP increased (p<0.05) the AID of starch and the SID of CP and most AA.
conclusionAddition of 6% SDP to diets based on wheat and barley (Canada and European Union diets) may increase the AID of starch and the SID of CP and AA from other ingredients in the diet. Therefore, the SID of CP and AA in diets containing SDP is not always additive in wheat and barley-based diets.
