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
Malaria is a significant public health problem in several tropical countries including Thailand. The prevalence of Plasmodium vivax infection has been increasing in the past decades. Plasmodium vivax merozoite surface protein (PvMSP) gene encodes a malaria vaccine candidate antigen. Its polymorphic nature leads to antigenic variation, the barrier for vaccine development, drug resistance, and potential for multiple-clone infections within the malaria patients. The objective of this study was to investigate the genetic diversity of PvMSP1 and PvMSP3 gene in P. vivax populations in Thailand. A total of 100 P. vivax isolates collected from the western (Kanchanaburi and Tak Provinces) and southern (Ranong Provinces) regions along the Thai-Myanmar border were analyzed using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Analysis of the F1, F2, and F3 regions of PvMSP1 revealed 5, 2, and 3 allelic variants, respectively. Three major types of PvMSP3-α and two major types of PvMSP3-β were identified based on the PCR product sizes. After digestion with restriction enzymes, 29, 25, 26, and 18 patterns were distinguished by RFLP for PvMSP1 (F2, Alu I), PvMSP1 (F2, Mnl I), PvMSP3-α, and PvMSP3-β, respectively. Combination of each family variant (PvMSP1 and PvMSP3) resulted in high genetic polymorphism of P. vivax population. Additionally, using PvMSP1 polymorphic marker revealed a significant association between multiple-genotype infections and P. vivax parasitemia. The results strongly supported that P. vivax populations in the endemic areas along the Thai-Myanmar border are highly diverse.
