While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Are TP53 Arg72Pro and MDM2 T309G polymorphisms associated with bladder cancer risk? A meta-analysis
Abstract
Background: We still do not know the exact cause of bladder cancer (BC).
Objectives: Evaluation of the effect of TP53 Arg72Pro and MDM2 T309G polymorphisms with the risk of Bladder cancer.
Methods: A literature search was conducted followed by a meta-analysis. Then, sensitivity and subgroup analyses were performed. 14 relevant studies were included in the quantitative analysis.
Results: No statistically significant associations were found. The results of the subgroup analysis revealed a significant association in the Turkish population for T309G: G vs. T (P-value= 0.015; OR 95%CI= 1.51 [1.084; 2.125]), GG vs.TT (P-value= 0.009; OR 95% CI= 2.60 [1.262; 5.370]). Sensitivity analysis revealed a significant association between the Arg72Pro: C vs G (OR= 1.22, 95% CI [1.05; 1.40]), CC vs. GG (OR= 1.54; 95% CI [1.13; 2.09]), CC+CG vs. GG (OR= 1.24; 95% CI [1.01; 1.53]), CC vs. CG+GG (OR= 1.33; 95% CI [1.01; 1.74]), and T309G: G vs. T (OR= 1.30; 95% CI [1.07; 1.57]), GG vs. GT+TT (OR= 1.53; 95% CI [1. 10; 2.11]), GG vs. GT (OR=1.44; 95% CI [1.02; 2.02]), GG vs. TT (OR= 1.88; 95% CI [1.25; 2.82]) with BC occurrence.
Conclusion: The T309G polymorphism was found to be a predisposing allele for BC in Turkish population.
