Our trials were conducted across five countries: India, Kenya, Nepal, Uganda and the Philippines. In all settings, schooling was disrupted owing to the COVID-19 pandemic ... One treatment included a set of SMS messages ... A second treatment provided additional weekly 20 min phone call tutorials for 8 weeks.",

We find the programme yields 3.6 LAYS per US$100, ranking in the top 10 out of 150 education interventions reviewed ... The SMS-only intervention ... can be ... 41.1 learning-adjusted years of schooling (LAYS) per US$100. However, whereas phone and SMS effects were consistent across all countries, the effects in the SMS-only arm varied across contexts.",

  "searched": "Read the counted primary passage and the Nature primary article, checking population, countries, intervention arms, period, outcome translation, denominator, and whether the pooled cost figure applies to phone calls, SMS, or both. The result is a five-country randomized-trial programme for primary-school children during COVID-19-related school disruption; the article defines LAYS as a high-quality year of schooling gained and reports 3.6 LAYS per US$100 for the programme, while SMS-only cost-effectiveness is separately reported as 41.1 LAYS per US$100 and has mixed effects."
