Supplementation of protease with low protein diets improves incidence of frequency and nitrogen metabolism in weaned pigs.

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 purpose of this study was to determine the effect of different crude protein (CP) levels and protease (PT) supplementation on effect in weaned pigs. A total of 24 barrow weaned pig, 7-week-old and with an initial weight of 10.94 ± 1.26 kg, were performed in the 2-week experiment. The experiment followed a 2 × 2 factorial design with two levels of CP (18.78% and 16.92%) and two levels of PT supplementation (0, 0.1%). No difference was observed in growth performance by the variations in CP and PT levels. In fecal score, the low CP (LP) diet showed an increased frequency of 0 scores compared to the high CP (HP) diet. The apparent total tract digestibility (ATTD) of dry matter (DM) increased during the first week in the LP diet compared to the HP diet. At second week, the ATTD of DM was increased in the LP diet compared to the HP diet and the ATTD of CP increased in the PT10 compared to the PT0. Also, DM had an interaction between CP and PT. In the ATTD of amino acids in the first week, the LP diet had a higher methionine digestibility than the HP diet, and the tryptophan digestibility was higher in the HP diet than the LP diet. In second week, the PT10 diet had a higher digestibility than the PT0 diet for indispensable amino acids excluding lysine and tryptophan, and for methionine, the LP diet had a higher digestibility than the HP diet. In the ATTD of indispensable amino acids, the digestibility of threonine, isoleucine, leucine, arginine, and methionine was higher in the PT10 diet compared to the PT0 diet.
