The PNH French Working Group Experience: Building a Strong Network of Cytometrists.
Review in International journal of laboratory hematology, 2026. 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
introductionThe PNH working group was created in 2010 to initiate a workshop on testing white blood cells to share international recommendations.
methodsThirty-five French and Belgian laboratories equipped with 2- or 3-laser cytometers applied three different panels with or without FLAER reagent in 305 samples. This multicenter study demonstrated the interplatform applicability of setting harmonization and the benefits of using a harmonized gating method. A 10
resultsFollowing this workshop, the group has developed a quality control scheme since 2013 to improve PNH diagnosis practices. This annual program includes two surveys, a virtual one and one based on fresh whole-blood sample analysis. Over the last 10 years, the regular participation of the French-speaking registered centers has demonstrated their strong commitment to our program, which offers various PNH clinical situations. Alongside, the conformity of the final reports provided by the participants has increased to 96%.
conclusionIn 2016, our PNH working group initiated a nationwide multicenter prospective observational study, collecting all PNH cases or GPI-deficient cells above 0.01% to monitor the long-term evolution of minor PNH clones < 1% and to further investigate the relevance of classifying type II and type III PNH cells in WBCs in clones > 1%. The strong network of cytometrists built led us to create in 2018 the French-speaking flow cytometry association in Hematology, namely CytHem, to harmonize the diagnostic practices in various hematological diseases.
