Giardia duodenalis: a freeze-fracture, fracture-flip and cytochemistry study.
Article in Parasitology research, 1991. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The freeze-fracture technique was used to study the structural organization of the membranes of trophozoites of the protozoon Giardia duodenalis. No special array of intramembranous particles was observed in the membrane lining the protozoon body or the flagella. A large globular protuberance located in the ventral region displayed several small circular indentations similar to those seen in the dorsal region. These also occurred on the parasite surface as revealed in fracture-flip replicas. A large number of vesicles were observed below the plasma membrane; they corresponded to an acidic compartment as indicated by fluorescence microscopy of acridine orange-stained cells and contained acid phosphatase as indicated by cytochemistry. In addition, gold-labeled macromolecules (albumin, peroxidase, transferrin, and low-density lipoprotein) accumulated in the vesicles. These observations suggest that the peripheral vesicles of trophozoites are part of the endosomal-lysosomal system of G. duodenalis.
