Characteristics of the use of cold combination products among older ambulatory patients at the National Hospital Organization Tochigi Medical Center in Japan: a retrospective single-center observational study.
Observational study in BMC research notes, 2017. 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
objectiveThis study aimed to determine the frequency and characteristics of prescriptions of cold combination products among older ambulatory patients. A retrospective observational study was conducted using electronic medical records. All patients aged 65 years or older who continued visiting internal medicine physicians for at least 1 year were included. The primary outcome was the prescription of cold combination products by any physicians in National Hospital Organization Tochigi Medical Center during a 1-year follow-up.
resultsSeven hundred fifty-six patients were included. The mean age was 75.4 years, 392 (51.9%) were men, the mean Charlson Comorbidity Index was 1.8, and the mean number of medications was 4.9. The proportion of patients who were prescribed cold combination products during the 1-year follow-up was 6.1% (95% confidence interval 4.4-7.8%). The prescription of cold combination products was not significantly associated with age (p = 0.11) or Charlson Comorbidity Index (p = 0.93) but was associated with an increasing number of medications (p < 0.001). A substantial proportion of older ambulatory patients were exposed to cold combination products during a 1-year follow-up.
