Relapsed Childhood Acute Lymphoblastic Leukemia: Experience from a Single Tertiary Center in Thailand.
Article in Asian Pacific journal of cancer prevention : APJCP, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe outcomes of relapsed childhood acute lymphoblastic leukemia (ALL) in developed countries have improved over time as a result of risk-adapted, minimal residual disease-directed therapy, hematopoietic stem cell transplantation, and immunotherapy. There are few studies that have examined survival in relapsed childhood ALL in resource-limited countries. Therefore, this study aimed to assess the prognostic factors and survival outcome of relapsed childhood ALL in a major tertiary center in Southern Thailand.
methodsThe medical records of patients with ALL aged <15 years between January 2000 and December 2019 were retrospectively reviewed. The Kaplan-Meier method was used to depict the overall survival (OS).
resultsA total of 472 patients with ALL were enrolled and relapsed ALL was found in 155 (32.8%) patients. Of these, 131 (84.5%) and 24 (15.5%) had B-cell and T-cell phenotypes, respectively. One hundred thirteen (72.9%) and 42 (27.1%) patients had early and late relapses, respectively. The most common site of relapse was bone marrow in 102 patients (65.8%). One hundred twenty-eight (82.6%) patients received treatment while 27 (17.4%) patients refused treatment. The 5-year OS of all relapsed patients was 11.9%. The 5-year OS among the patients with early relapse was significantly lower than in the patients with late relapse (5.3% vs. 29.1%, respectively, p <0.0001). Site and immunophenotype were not associated with survival of relapsed ALL. The median survival times among the patients who received and refused relapse chemotherapy were 11.8 and 3.1 months, respectively (p <0.0001).
conclusionThe relapse rate accounted for one third of patients with ALL with the 5-year OS of 12%. Early relapse and those who refused treatment were associated with poor survival outcome.
