| Small sample sizes limit the use of inferential statistics and decrease the external validity or generalizability of the findings. |
| The generalizability of the findings would also have been improved with a larger and more representative sample of mothers and children. |
| The heterogeneity among studies for the latter outcome indicates the questionableness of the generalizability of this estimate. |
| To enhance its generalizability, this study did not restrict its sample in terms of partner domiciles or host country locations. |
| Furthermore, studies should include comparable groups of patients to increase the generalizability of the results. |
| Although lack of generalizability is often cited as the major shortcoming of randomization tests, other limitations have also been discussed. |
