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
Mitogen-activated protein kinases (MAPKs), also termed extracellular signal-regulated kinases (ERKs), are cytoplasmic and nuclear serine/threonine kinases involved in signal transduction of several extracellular effectors. In mammals, ERKs participate in the regulation of spermatogenesis, mature spermatozoa motility, hyperactivation, and the acrosome reaction. To investigate ERK functions in Eriocheir sinensis reproduction, we successfully cloned the full-length ERK from the testis of E. sinensis (ES-ERK). The 1098-nucleotide open reading frame encodes a 365-amino-acid protein with a predicted molecular weight of 42 kDa. Expressions of ES-ERK in different tissues and testis development stages were detected by the quantitative RT-PCR and Western blotting. ES-ERK is expressed relatively highly in the testis. The expression of ES-ERK protein gradually increased in the spermatid stage, reaching a peak in sperm stage. Western blotting showed a similar expression pattern for the total ES-ERK protein, but phospho-ERK (p-ERK) showed the higher expression in spermatid than sperm stage. We also used trypan blue and hematoxylin and eosin staining to identify structural changes in E. sinensis spermatozoa during the process of acrosome reaction (AR). After stimulating the process of AR, the ES-ERK has translocated from the nucleus to the acrosomal tubule. This result suggested that the ERK MAPK might be involved in the regulation of the E. sinensis acrosome reaction.
