Fluorescent in situ hybridization can be used as a complementary assay for the diagnosis of Tropheryma whipplei infection.
Article in Infection, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundImmunohistochemistry and Periodic acid-Schiff (PAS) staining have been routinely used for the diagnosis of Whipple's disease (WD). However, these methods present limitations. As a result, the last years, Fluorescence in situ hybridization (FISH) has been increasingly used as a complementary tool for the diagnosis of WD from various tissue samples. CASE REPORT: In this study, we visualized, by FISH, Tropheryma whipplei within macrophages of a lymph node from a patient with WD. Moreover, we report in this study a patient with a pulmonary biopsy compatible with WD by PAS, immunostaining and FISH, although the specific molecular assays for T. whipplei were negative. Sequencing analysis of the 16S rDNA revealed a T. whipplei-related species with unknown classification.
conclusionFISH can be a valuable method for the detection of Tropheryma species in formalin-fixed paraffin-embedded tissues. FISH cannot replace the other already approved diagnostic techniques for WD, it can be used as a complementary tool and can provide supplementary information in a relatively short time.
