Effect of graduated drug therapy for moderate-to-severe chronic insomnia on the severity of disease: an observational study in Germany.
Observational study in Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine, 2025. 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
STUDY
objectivesSevere chronic insomnia is a common sleep disorder that is mostly persistent and needs to be treated. Pharmacologic treatment options and guidelines are sparse, particularly for long-term treatment. Our study aimed to investigate a graduated therapy scheme for moderate-to-severe chronic insomnia in practice, considering the effects on self-reported sleep quality and quality of life.
methodsPatients with moderate-to-severe chronic insomnia were given appropriate medication according to a graduated therapy scheme, ranging from l-tryptophan (as the first choice, least potent) to Z-drugs and combination therapies (as the last option, most potent). Each step of the graduated therapy scheme was tested for at least 4 weeks. Data related to sleep and quality of life were collected in questionnaire form (Insomnia Severity Index, Pittsburgh Sleep Quality Index, Beck Depression Inventory, second edition, and Short Form 36 Health Survey) at baseline and during the course of the treatment after 1, 3, 6, 9, and 12 months.
resultsOf 86 eligible patients, 60.5% started treatment with l-tryptophan and 8.1% with melatonin. After 3 months, 12.5% were still taking l-tryptophan and 12.5% were taking melatonin. There was a significant decrease in mean Insomnia Severity Index, Pittsburgh Sleep Quality Index, Beck Depression Inventory, second edition, and Short Form 36 Health Survey scores after 3 months of treatment for all patients in the study (n = 64). After 6 months, 22.2% were still taking l-tryptophan, melatonin, or agomelatine, and the remainder had switched to more potent drugs such as antidepressants, hypnotics, daridorexant, or combination therapies.
conclusionsA significant number of patients already responded favorably to mild sleep medications, whereas others demonstrated a need for more potent treatments. Ongoing monitoring will evaluate the long-term effectiveness of both approaches. CLINICAL
