Fragmented Red Cell as a Possible Favorable Prognostic Marker of Hematopoietic Stem Cell Transplantation Associated Thrombotic Microangiopathy.
Article in Journal of clinical laboratory analysis, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundFragmented red cell (FRC) by automated hematologic analyzer is known to detect schistocyte. In this study, it is noted that FRC might be a favorable prognostic marker of hematopoietic stem cell transplantation associated thrombotic microangiopathy (TA-TMA).
methodsThe peripheral blood samples and clinical data of 89 patients were collected. The diagnosis of TA-TMA was defined by the Blood and Marrow Transplant Clinical Trials Network's criteria and schistocyte or both schistocyte- and FRC-positive cases and other parameters fulfilled are regarded as TA-TMA.
resultsSchistocyte and FRC displayed a correlation coefficient of 0.461 (P < 0.001) by Spearman's method. The diagnostic concordance of TA-TMA using schistocyte and FRC was 92.1% with kappa index of 0.531 (P < 0.001). The number of diagnosed patients and mean survival month were as follows: TA-TMA by schistocyte, 8 (8.9%), 13.5 month; TA-TMA by schistocyte and FRC, 7 (7.8%), 40.4 month; No TMA, 74 (83.1%), 38.3 month, respectively. Kaplan-Meier survival analysis by log-rank method of the patient with TA-TMA by schistocyte and rest of the group showed statistical significance (P < 0.01).
conclusionAs evidenced by the data, FRC might be a favorable prognostic marker for TA-TMA, but additional studies with larger patients groups are required for validation of clinical applications.
