Dataset and code for: Game elements, not games: A systematic review, bibliometric analysis and meta-analysis of gamification and academic achievement in higher education across Asia and the Middle East

Version 2 of the dataset accompanies a revised review that separates gamification from game-based learning and serious games. It contains the protocol with amendments A1–A12 and the Scopus search string; the 350 studies that met the original criteria with later corrections (343 remain); the construct codebook, first-pass codes and a blind second coding of a random sample of 100 studies; the per-study extraction cascade of the 66 studies in the meta-analytic frame and a re-screen of 28 studies outside it; extraction logs of five rounds; every effect with its comparison condition, risk of bias (RoB 2 / ROBINS-I), clusters, flags and notes, and the alternative contrasts; pooled models with Knapp–Hartung intervals, subgroup, sensitivity and leave-one-out results with a metafor 5.2.1 cross-check; the comparison of subregions; and the Python and R code that regenerates every number and figure of the article.
