Continuous or Fixed-Duration Maintenance Therapy in Multiple Myeloma.
Trial report in The New England journal of medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01863550 (Randomized Phase III Trial of Bortezomib, Lenalidomide, and Dexamethasone), which is not on this map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundCurrent treatment of newly diagnosed multiple myeloma involves lenalidomide maintenance therapy given until disease progression. The appropriate duration of maintenance therapy with lenalidomide has been unclear.
methodsIn this phase 3 trial, we enrolled patients with standard-risk newly diagnosed multiple myeloma who were not undergoing up-front autologous stem-cell transplantation. After induction treatment with a proteasome inhibitor-lenalidomide combination, patients were randomly assigned to receive indefinite-duration (continuous) lenalidomide or fixed-duration lenalidomide (for 2 years). The primary end point was overall survival; the trial had 80% power to detect a 50% increase in median survival (from 5 years to 7.5 years), with a two-sided alpha level of 5%, 395 patients undergoing randomization, and 204 deaths occurring during 9 years of follow-up.
resultsAt the end of induction, 516 patients were randomly assigned to the indefinite-duration group (260 patients) or the fixed-duration group (256 patients). At a median follow-up of 86 months, overall survival did not differ significantly between the groups. With 80 deaths in each group, overall survival at 7 years was 68.6% in the indefinite-duration group and 69.0% in the fixed-duration group (difference, -0.4 percentage points; 95 confidence interval [CI], -9.0 to 8.3; P = 0.93). Progression-free survival at 7 years was 36.1% in the indefinite-duration group and 29.7% in the fixed-duration group (difference, 6.4 percentage points; 95% CI, -2.6 to 15.4). The 5-year cumulative incidence of second primary cancers, excluding nonmelanoma skin cancer, was 11.2% with indefinite-duration lenalidomide and 8.3% with fixed-duration lenalidomide. More adverse events occurred with indefinite-duration lenalidomide; the incidence of nonhematologic events of grade 3 or higher was 48.2% with indefinite-duration therapy and 31.5% with fixed-duration therapy.
conclusionsIn this phase 3 trial involving patients with standard-risk newly diagnosed multiple myeloma who were not undergoing up-front autologous stem-cell transplantation, indefinite-duration maintenance therapy after induction therapy did not result in significantly longer overall survival than fixed-duration maintenance therapy.
