https://www.pubmed.ai will generate a deep research report on that specific query involving checkpoint inhibitors and non small cell lung cancer for free. It won't have the nice comparison table that Elicit can generate. Also, pubmed.ai cannot parse a query as complex as the one used for Elicit, but you can paste the Elicit query into OpenAI's chatGPT and ask it to translate the query into a form that Pubmed can parse. Pubmed.ai was able to parse the chatGPT generated query string "("Checkpoint inhibitors"[Title/Abstract] OR "immune checkpoint blockade"[Title/Abstract])AND ("non-small cell lung cancer"[Title/Abstract] OR NSCLC[Title/Abstract])AND ("platinum-based chemotherapy"[Title/Abstract] OR cisplatin[Title/Abstract] OR carboplatin[Title/Abstract])AND (bevacizumab[Title/Abstract] OR "anti-VEGF"[Title/Abstract])AND ("PD-L1 expression"[Title/Abstract] OR "PD-L1 level"[Title/Abstract])AND (effectiveness[Title/Abstract] OR efficacy[Title/Abstract])AND (safety[Title/Abstract] OR toxicity[Title/Abstract])."
