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
objectiveTo screen and identify serum biomarkers for childhood hepatoblastoma (HB).
methodsThe serum samples from 30 children with hepatoblastoma (HB), 20 children with systemic inflammatory response syndrome, and 20 normal children were treated with magnetic bead-based weak cation exchange chromatography. The platform of surface-enhanced laser desorption/ionization-time of flight-mass spectrometry (SELDI-TOF-MS) was used to eliminate the interference of inflammatory factors and to screen out the differentially expressed proteins in serum between tumor group and normal group. After the purification and separation of target proteins were performed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis, matrix-assisted laser desorption/ionization-time of flight-mass spectrometry was used to determine their amino acid sequences. The SwissProt database was searched for matched proteins. Finally, real-time PCR and ELISA were used to verify and measure the expression of target proteins.
resultsAfter SELDI-TOF-MS was used for screening and elimination of the interference of inflammatory factors, a differentially expression protein with a mass-to-charge ratio of 9 348 Da was found in serum between HB group and normal group, and the HB group had significantly lower expression of this protein than the normal group (p<0.05). This protein was identified as apolipoprotein A-1 (Apo A-I). Real-time PCR and ELISA verified the low mRNA and protein expression of Apo A-I in serum in the HB group and high expression in serum in the normal group.
conclusionsApo A-I can be used as a non-inflammatory protein marker for HB and has a certain value in the early diagnosis of HB.
