1 · What the graph read from it

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.

2 · The registry

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

<p>Introduction: In this study, we examine the outcomes and trends of second-side cochlear implant (CI) in adults as measured by change in speech perception scores, with a focus on those meeting age requirements for Medicare.

methodsThis is a retrospective cohort study performed at a tertiary academic center. The investigation included adult patients with bilateral hearing loss receiving sequential, bilateral CI between 2001 and 2020. Bilateral speech perception scores under best aided conditions were compared following first- and second-side CI using Arizona Biomedical (AzBio) Sentence Test, Consonant-Nucleus-Consonant word (CNC-W), and Hearing in Noise Test (HINT). Individual changes in audiometric scores and trends in implant age and inter-implant interval were evaluated.

resultsA total of 162 individuals were included in this study. 50 patients with AzBio scores, 40 patients with HINT scores, and 72 patients with CNC-W scores demonstrated mean improvements of 11.8 (95% CI: [5.7-17.9]), 6.7 (95% CI: [0.4-13.7]), 12.0 (SD: 25.3), and 11.5 (95% CI: [7.3-15.7]) points, respectively, following second-sided CI. Patients aged 65 and older experienced similar magnitude of improvement as younger patients (t-tests: AzBio: 95% CI: [-16.7, 17.4]; HINT: 95% CI: [-34.6, 0.5]; CNC-W: 95% CI: [-10.7, 13.1]). Longer time interval between implants was associated with reduced improvement in CNC-W in the overall population (β: -2.9, 95% CI: [-5.5 to -1.2]) and the elderly population (β: -4.24, 95% CI: [-6.1 to -2.8]) specifically. Over time, there were no significant changes in age of CI-1 implant or audiometric scores after bilateral CI, but there was a decrease in inter-implant interval.

conclusionsIntervention with a second-sided cochlear implant was associated with improved speech recognition scores and this benefit extended to patients aged 65 and over. Decreased inter-implant interval is associated with an increase in improvement. </p>.
