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
purposeTo examine differences in hearing loss etiologies and cochlear implant outcomes between Jewish and Arab pediatric populations in Israel, addressing the understudied influence of ethnic disparities.
methodsA retrospective cohort study was conducted on 120 children (53 Jewish, 67 Arab) who underwent 171 cochlear implantations at our hospital between May 2018 and December 2022. Data included demographics, socioeconomic status, etiology, and audiological outcomes. Outcomes were assessed using pure tone averages (PTA) and speech thresholds (SRT/SDT) at seven-time points over 60 months. Predictors of early and long-term outcomes were evaluated using multivariate ANCOVA models.
resultsJewish and Arab children had comparable demographics, but significant socioeconomic differences (399.5 ± 378.7 vs. 110.3 ± 181.6, p < 0.0001). Hearing loss etiologies differed significantly: Arab children showed predominantly congenital causes (68.7%), mainly genetic (62.7%), while Jewish children had higher acquired causes (54.7%), primarily CMV-related (52.5%). PTA thresholds were significantly better in Jewish patients at 1-4, 25-36, and 49-60 months post-implantation (p < 0.05). SRT/SDT thresholds did not differ. Multivariate analysis identified ethnicity, younger age at surgery, primary implantation status, and etiology as significant predictors of outcomes. Socioeconomic rank was not independently associated with outcomes.
conclusionEthnic differences in cochlear implant outcomes persist despite Israel's universal healthcare system, reflecting the impact of unmeasured social, cultural, and behavioral factors. These findings underscore the importance of individualized treatment strategies that consider both biological and sociocultural factors to optimize outcomes for all populations.
