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
backgroundMethotrexate (MTX) intolerance in juvenile idiopathic arthritis (JIA) frequently leads to discontinuation due to anticipatory and associative gastrointestinal symptoms. Eye Movement Desensitization and Reprocessing (EMDR) has successfully been used in MTX intolerance, with lasting effects but frequently diminishing efficacy over time. BLAST (bi-lateral alternating stimulation tactile) wristbands utilize a similar process to EMDR. The aim of this study was to determine if utilization of BLAST wristbands could improve and prolong the effect of EMDR on patients with MTX intolerance.
methodsConsecutive patients admitted to the German Center for Pediatric and Adolescent Rheumatology with JIA and signs of MTX intolerance from October 2016 until March 2024 were included in this study. Treatment was performed using an adapted 8 phase EMDR protocol implementing BAST wristbands. Initial patients were treated with EMDR, subsequent patients additionally with BLAST wristbands. Health-related quality of live was determined using the PedsQL. Measurements of MISS (Methotrexate Intolerance Severity Score) and PedsQL were taken at 4 time points: directly before and after (MISS only) treatment, as well as 4 and 12 months after treatment. Changes in MISS and PedsQL were compared using descriptive statistics and repeated measures ANOVA.
results87 patients with MTX intolerance were included, 53 in group 1 without BLAST wristbands and 34 in group 2 which were concurrently treated with BLAST wristbands. All patients reported marked improvement of MTX intolerance symptoms (mean MISS score group 1: 15.0 ± 5.5 before treatment, 1.3 ± 1.5 after treatment, group 2: 16.8 ± 5.6 and 2.5 ± 2.5, respectively). After 4 and 12 months, MISS in group 1 was 8.1 ± 7.1 and 8.7 ± 8.4, and in group 2: 7.1 ± 6.3 and 6.5 ± 5.7. A repeated measures ANOVA showed a significant difference between the MISS results over time (F(3,114) = 64.6, p < 0.001), and also demonstrated a significant difference of the PedsQL results between the two groups over time (F(2,64) = 8.9, p < 0.001).
conclusionTreatment with Eye Movement Desensitization and Reprocessing (EMDR) could present an effective treatment of MTX intolerance, and using BLAST wristbands, further potential improvement is possible.
