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
purposeAllogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment for advanced hematologic malignancies. HSCT using human leukocyte antigen (HLA)-mismatched donors is historically associated with inferior survival. Patients from underrepresented racial and ethnic groups more frequently rely on HLA-mismatched donors. We hypothesized that post-transplant cyclophosphamide (PTCy) based graft versus host disease (GVHD) prophylaxis would improve outcomes for HSCT recipients using peripheral blood stem cells (PBSCs) from HLA-mismatched unrelated donors (MMUDs) by reducing the risk of GVHD.
methodsThis phase II, nonrandomized, multicenter trial assessed PBSCs in the setting of a GVHD prophylaxis regimen of cyclophosphamide, tacrolimus, and mycophenolate mofetil in two adult strata: myeloablative conditioning (MAC) and reduced-intensity or nonmyeloablative (RIC/NMA) conditioning before HSCT from a MMUD. The primary objective was to estimate 1 year overall survival (OS) for each stratum. Key secondary end points included incidences of acute and chronic GVHD.
resultsA total of 145 patients enrolled, with 59% self-identifying within an underrepresented group. The 1 year OS was 83.8% (95% CI, 73.1% to 90.4%) for MAC and 78.6% (95% CI, 67% to 86.5%) for RIC/NMA. Incidences of grades III to IV acute GVHD at 6 months were 8% (95% CI, 3.2 to 15.6) for MAC and 10% (95% CI, 4.4 to 18.4) for RIC/NMA. Moderate/severe chronic GVHD at 1 year was 10.3% (95% CI, 4.4 to 18.9) for MAC and 8.6% (95% CI, 3.5 to 16.6) for RIC/NMA. 32% of patients whose donors matched at fewer than seven of eight HLA alleles had similar OS compared with those with donor matched at seven of eight alleles.
conclusionPTCy-based GVHD prophylaxis after MMUD HSCT with PBSC grafts results in favorable 1 year OS. Using MMUDs expands donor availability to all patients regardless of ancestry (ACCESS; ClinicalTrials.gov identifier: NCT04904588).
