Serum Bcl-2 Levels in Patients with β-Thalassemia Minor: A Pilot Study.
Article in Turkish journal of haematology : official journal of Turkish Society of Haematology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveAnti-apoptotic proteins such as Bcl-2 and Bcl-xL may play a role in the survival of erythroid progenitor cells. Information about these proteins in patients with β-thalassemia minor is limited. We aimed to determine the levels of serum Bcl-2 in patients with β-thalassemia minor. MATERIALS AND
methodsNinety-seven patients (60 females and 37 males with mean age of 29±21 years) with β-thalassemia minor were enrolled in this study. The diagnosis of β-thalassemia minor was based on whole blood counts, family history, and HbA2 levels estimated by high-performance liquid chromatography. The control group comprised 23 healthy adults (17 females and 6 males with mean age of 58±9 years) without anemia. The levels of serum Bcl-2 were measured by enzyme-linked immunosorbent assay. Mann-Whitney U tests were used in statistical evaluation and p<0.05 was accepted as statistically significant.
resultsAlthough there was no statistically significant difference between patients with β-thalassemia minor and the control group for the level of serum Bcl-2 (p>0.05), these levels were higher in β-thalassemia minor patients than controls.
conclusionThere are damaged beta chains in β-thalassemia minor. Therefore, it is expected that premature death of red blood cells may occur due to apoptosis. The mean age of the control group was higher than that of the β-thalassemia minor group; this may be why Bcl-2 levels were higher in the β-thalassemia minor group. It is known that older age constitutes a risk for increased apoptosis. Other proteins (Bad, Bax, etc.) and pathways [CD95 (Fas) ligand] associated with apoptosis should be evaluated in future studies including more patients.
