The Tree Drawing Test in Evolution: An Explorative Longitudinal Study in Alzheimer's Disease.
Article in American journal of Alzheimer's disease and other dementias. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectiveTo study the evolution of the Tree Drawing Test (TDT) in a group of Alzheimer's disease (AD) patients.
methodsA total of 33 AD patients were consecutively evaluated by Mini Mental State Evaluation (MMSE) and TDT. The evolution of the TDT parameters, trunk-to-crown (TC) and space occupation (SO) index, were analyzed.
resultsThe median age at first visit was 79 years. Globally, trees drawn by patients showed an evolution characterized by a progressive reduction of the crown compared to the trunk. TC index showed a significant linear growth change (2.52 points per year) while SO index did not significantly increase. No significant associations were found examining the relations between MMSE and TC and SO index.
conclusionsTDT could represent a complementary technique to the main neuropsychological screening tests for orienting cognitive impairment diagnosis and an aid in following the evolution of cognitive impairment over time in AD patients.
