[Alzheimer dementia: course and burden on caregivers : Data over 18 months from German participants of the GERAS study].
Observational study in Der Nervenarzt, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The GERAS study is an international observational study with dementia patients of the Alzheimer type (AD) and their caregivers in everyday care. The 18-month data recorded in Germany are presented. Disease progression, medical and psychosocial consequences for both patients and caregivers were recorded using commonly used tests in clinical care: the mini mental status examination (MMSE), Alzheimer's disease assessment scale (ADAS-Cog14), Alzheimer's disease cooperative study activities of daily living inventory (ADCS-ADL), neuropsychiatric inventory (NPI-12), resource utilization in dementia (RUD) and the Zarit burden interview (ZBI). Definition of AD severity level (MMSE): 21-26 mild (miAD), 15-20 moderate (moAD), <15 moderately severe to severe (m/sAD). For the 550 participants (mean age: 75.2 years, SD 7.6 years), miAD (41.5%), moAD (28.4%) and m/sAD (30.2%), the MMSE worsened: in miAD by -2.4 (CI -3.1/-1.7), in moAD by -3.9 (CI -5.0/-2.8) and in m/sAD by -2.5 (CI -3.5/-1.5) at 18 months and the ADAS-Cog14 by 6.2 (miAD-CI 4.6/7.8) and 7.1 points (moAD CI 3.9/10.3). Changes in overall ADCS-ADL amounted to -8.4 (CI -10.1/-6.2) for miAD, -12.9 (CI -15.3/-10.4) for moAD and -10.2 points (CI-12.8/-7.7) for m/sAD. Caregiver burden (NPI-12) rose in miAD by 1.2 points (CI -0.2/2.2), in moAD by 3.4 (CI 1.8/5.1) and in m/sAD by 1.5 points (CI 0.2/3.3). At study start, the total time required by caregivers (RUD) was 3.1 h/day (SD 5.4 h/day) for miAD, 6.6 (SD 7.5) for moAD and 12.7 (SD 9.3) for m/sAD. With 4.4 (SD 9.4) h/day, the increase after 18 months was highest in moAD. Caregiver burden (ZBI) increased most markedly in moAD with 7.2 (CI 4.2/9.7), 90.7% of the patients received antidementia drugs, while 26.6% received psychotropic medication.
