Contributions Jos Vaessen (JV), Maren Duvendack (MD), Hugh Waddington (HW) and FransLeeuw (FL) contributed to the writing and revising of this systematic review. JV, Ana Rivas and Ger van Gils (GG) contributed to the design of the review and the information retrieval activities associated with the review. In the quality assessment of selected studies, we distinguish between assessment of methodological quality, carried out by MD, Richard Palmer Jones (RPJ) and HW, and assessment of the quality of the theoretical framework of selected studies carried out by GG and FL. The meta-analysis was conducted by MD, RPJ and HW, with additional support from Jorge Hombrados. The qualitative synthesis was conducted by GG, FL and JV. Nathalie Holvoet and Johan Bastiaensen helped developing the theoretical framework on microcredit and empowerment. Ruslan Lukach contributed to methodological design. JV will be responsible for updating this review as additional evidence accumulates and as funding becomes available.
