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
Persian sturgeon (Acipenser persicus) is a critically endangered species, mainly due to overexploitation for its caviar. The permanence of populations of this species in the Caspian Sea is fully dependent on restocking programs. Accordingly, it is considered as an interesting target for aquaculture for both restocking and commercial purposes. In addition, as a Chondrostei, it exhibits one of the slowest rates of molecular evolution among vertebrates and is propounded as an excellent candidate for phylogenetic analysis and evolutionary biology. In this study, the early ontogeny of some key digestive enzymes precursors was determined at molecular level, aiming to obtain basic knowledge on the acquisition of digestive capacity of this species, and at the same time, to advance in its phylogenetic status from the point of view of digestion. For this purpose, A. persicus cDNAs for β-actin (actb; used as an internal reference gene), bile-salt activated lipase (cel), trypsinogen 1 (try1), pepsinogen (pga), and gastric proton pump (atp4a) were amplified and cloned, and their subsequent expressions were measured by quantitative real-time PCR during the first 34 days post hatch (dph). Two isoforms for pga and at least six for try1 were obtained in this study, probably due to the additional genome duplication which sturgeons suffered along evolution. Phylogenetic analysis of the deduced amino acids sequences from the studied genes demonstrated that this species has a close evolutionary distance to Holostei, coelacanths, and tetrapods, including amphibians, reptiles, birds and mammals. According to our results, expression of all the genes increased gradually over time and reached maximum levels around 18 dph. This pattern, which was comparable to length and weight data, could indicate that around 3 weeks after hatching, the digestive capacity of the Persian sturgeon changes from larval to juvenile mode.
