Survival among the older adults with clinical signs of Lewy body dementia in 40 Swedish nursing homes: a 6-year follow-up study.
Observational study in BMJ open, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectivesTo investigate survival among elderly residents of Swedish nursing homes (NHs), with specific focus on those with two or more signs of Lewy body dementia (LBD).
designProspective observational study.
settingNHs in Malmö, the third largest city in Sweden.
participantsThe study population was older adults (aged ≥65 years) living in the 40 NHs in Malmö. Clinical data were collected with a customised questionnaire assessing core clinical LBD signs. Patients were categorised based on 0-1 or 2-4 LBD signs. The head nurse at each NH collected the study data: LBD questionnaires, electronic medication lists and electronic medical records from 2012 to 2013.
main outcome measures80-month mortality.
resultsFive hundred and fifty-eight (96%) of the residents were deceased at follow-up; among these, mean (95% CI) overall survival time was 29 (28-31) months. Mean survival differed between the LBD groups; those with 0-1 LBD signs lived 8 months longer than those with 2-4 LBD signs. Mortality risk for residents in the LBD 2-4 group was also significantly higher. HR adjusted for age and sex was HR (95% CI) 1.60 (1.30 to 1.97). Mortality risk was also significantly higher in residents with signs of fluctuating cognition 1.36 (1.15 to 1.62), rapid eye movement sleep behaviour disorder 1.49 (1.11 to 1.98), balance problems 1.36 (1.14 to 1.61) or rigidity 1.41 (1.18 to 1.68).
conclusionsThis large, longitudinal study shows the important survival effects of identifying and diagnosing older adults NH residents who have two or more LBD signs.
