Sometimes a paper comes down to just one diagram or table. Like the one above. There’s a few ins and outs to this study, a few whys and wherefores. And you should probably read the whole thing and take notes and follow up the references and maybe drop a line to the authors for clarifications. But there’ll be no getting around the fact that kids who had access to homegardens didn’t need vitamin A supplementation to avoid night blindness, whereas kids who didn’t, did. Thanks to Jess for the tip.
