Clinical significance of assessment of thrombospondin and placenta growth factor levels in patients with sickle cell anemia: two centers egyptian studies.

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
backgroundSickle cell disease has a worldwide distribution. Vaso-occlusive crisis (VOC) is one of the most important clinical features of the disease. Thrombospondin (TSP1) and Placenta growth factor (PlGF) have been reported to be involved in sickle cell diseases (SCD).
objectiveThe aim of this study was to assess the clinical significance of Thrombospondin and Placenta growth factor profiles in patients with sickle cell disease. PATIENTS AND
methodsThis study was carried out in sixty patients with sickle cell anemia who were attendants to Hematology units, Pediatric Departments, Tanta and Elmenofia University Hospitals in the period between December 2011 and May 2014 including thirty patients during vaso-occlusive crisis and thirty patients out of crisis. Also this study included twenty healthy children of matched age and sex as a control group. Serum TSP1 and PlGF levels were analyzed by ELISA.
resultsIn SCA patients with crisis the mean serum Thrombospondin level was 902.5±280.89 ng/mL; in SCA patients out of crisis the mean serum Thrombospondin level was 462.5 ± 190.2 ng/mL and in controls the mean value was 236.66±58.29 ng/mL. In SCA patients with crisis the mean serum Placenta growth factor level was 19.97±1.28 pg/ml; in SCA patients out of crisis the mean serum Placenta growth factor level was 13.12 ± 1.82 pg/ml and in controls the mean value was 9.89 ± 1.20 pg/ml. All paired comparisons for Thrombospondin and Placenta growth factor reached statistical significance (P< 0.001). There was significant positive correlation between serum Thrombospondin and Placenta growth factor levels in sickle cell anemia patients during crisis (r=0.848, p=<0.001).
conclusionsThis is the first study to show TSP1and PlGF concentration changes in patients with SCD in a large cohort study from Middle East, and to show correlation between both markers; therefore TSP1and PlGF may be useful VOC markers in SCD patients. RECOMMENDATION: To further assess TSP1 and PlGF as a marker of VOC in patients with SCD, further studies should be conducted to determine the exact point before VOC, when serum TSP1 and PIGF levels begin to increase. This requires monitoring of the TSP1 and PIGF levels in sickle cell patients out of crisis, showing how rapidly these levels increase just before VOC development.
