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
Indirect immunofluorescence on HEp-2 cell line (HEp-2-IIF) remains "gold standard" method for the detection of antinuclear antibodies (ANA). ANA is an operative definition, showing the possibility of autoantibodies (Aab) to bind nuclear, and cytoplasmic antigens. One of the major examples is represented by anti-mitochondrial antibodies (AMAs), which target proteins of the inner and outer mitochondrial membranes, located into the cytoplasm. The standard IIF on rat kidney/stomach/liver tissue sections, with the combined use of other commercial assays, may all be used in ordinary lab life to validate the AC-21 pattern on Hep-2 cells. The routine lab experience teaches that commercial kits cannot always be detected and define specific AMAs. In these cases the literature proposes the use of other homemade assays to detect AMAs as immunoprecipitation (IP) and Western blot (IP-WB). However, using IP or IP-WB is difficult to apply in a routine laboratory, because of numerous cases to process and the related troubles. Where find confirmation of the AC-21 pattern if line-immunoblot and other routine methods (ELISA, CLIA/FEIA assays) fail? We review AC-21 AMA-like sera from our patients (year 2022) and propose a revised diagnostic algorithm based on the combined use of IIF on Hep-2 cells, line immunoblot and IIF on rodent tissue as a third line method. We demonstrated that, particularly in cases where the second level test was unsuccessful, the application of IFI on rodent tissues became indispensable to verify the existence of AMAs.
