Coccidioides species determination: does sequence analysis agree with restriction fragment length polymorphism?
Article in Mycopathologia, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Fifteen Coccidioides isolates were previously examined for genetic diversity using restriction fragment length polymorphism (RFLP); two fragment patterns were observed. Two isolates demonstrated one banding pattern (designated RFLP group I), while the remaining 13 isolates demonstrated a second pattern (designated RFLP group II). Recently, molecular studies supported the division of the genera Coccidioides into two species: Coccidioides posadasii and Coccidioides immitis. It has been assumed that the species division corresponds to the RFLP grouping. We tested this hypothesis by amplifying the ribosomal DNA internal transcribed spacer region as well as the dioxygenase, serine proteinase, and urease genes from 13 isolates previously examined by RFLP and then sequencing the PCR products. The appropriate species for each isolate was assigned using phylogenetically informative sites. The RFLP grouping agreed with the Coccidioides species assignment for all but one isolate, which may represent a hybrid. In addition, polymorphic sites among the four genes examined were in agreement for species assignment such that analysis of a single gene may be sufficient for species assignment.
