| Is the sampling frequency, duration of study, and sample size (e.g. extrapolations, generalizations) appropriate for answering the question(s) posed by the study? |
| Study site selection | Is the choice of study site selection clear and justified? This decision will be based on the explanations provided by study authors regarding a study site’s relevance in answering research questions, and is particularly important for the selection of case and control sites in terms of their comparability |
| Sources of data | Are the sources of data reliable, complete and available in the article? Do authors acknowledge potential biases, consider potential confounding factors, and/or perform triangulation to ascertain research results? The reliability of data will be assessed based on the authors’ acknowledgement of potential biases and if triangulation is performed to ascertain research results |
| Results | Are the results clearly linked to the intervention? Is causation of the socioeconomic, environmental, and/or health outcomes clearly attributable to the wood energy activities? |
| Conclusion | Are the conclusions justified by the results presented? Are the authors’ conclusions about the impact of woodfuel value chain activities supported by their data? |
