Article in Atencion primaria, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 establish the prevalence and characteristics of insomnia and its relationship to other health problems, medication, socio-health status and sleep hygiene in the elderly over 65 years of age.
designCross sectional study of prevalence.
settingAlbacete (Castilla-La Mancha), 2004-2005.
participantsA non-institutionalized elderly patient population (n=424).
methodSemi-structured interview. Study variables were: sleep characteristics, socio-familial repercussions, sleep hygiene, health problems, medication, health care utilization and socio-demographic variables. Primary insomnia (PI) was diagnosed according to DSM-IV criteria.
resultsReported sleeping difficulties, 34.2%; in 95.7% the sleep disturbance was chronic. The most frequent repercussions were: sensation of insufficient night-time sleep (62.1%) and daytime tiredness or sleepiness (52.2%). 20.3% (95% CI, 16.5-24.1) met criteria for PI. Insomnia rates were significantly higher in females and in subjects maintaining irregular hours and expressing dissatisfaction with bedroom environmental conditions. Psychopharmaceuticals were regularly consumed by 26.9% of the subjects (95% CI, 22.7-31.1). The average number of health problems was higher in subjects with insomnia (2.4+/-1.6 compared with 1.7+/-1.5 in non-insomniacs; P<.001). By means of logistic regression, female gender (OR=2.8; 95% CI, 1.6-4.8) and the existence of 2 or more health problems (OR=2; 95% CI. 1.2-3.4) were associated with PI.
conclusionsPI affects approximately one fifth of people over the age of 65. It is more frequent in females and is related to the existence of other health problems, medication and inadequate sleep hygiene.
