Seasonal and gender-specific patterns in prescriptions for hypnotic and sedative medications in primary care.

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
Introduction: Population-level prevalence of sleep disorders can be assessed using prescription data for hypnotic and sedative medications. Such prescribing patterns exhibit seasonality that may be linked to variations in daylight exposure. The aim of this study was to analyze temporal trends in prescriptions for drugs with sedative-hypnotic properties. Methods: Prescription data for hypnotics and sedatives were analyzed retrospectively and stratified by month, year, and patient gender. Seasonal patterns, associations with day length, and the effects of transitions between daylight saving time and standard time were examined. Changes in prescription numbers during the COVID-19 pandemic were also assessed. Relative differences in prescription counts were evaluated using incidence rate ratios (IRR). Results: Prescription numbers were lowest in summer (May-August) and highest in winter and early spring. Increasing day length was significantly associated with reduced prescription rates. A decline in prescriptions occurred earlier and was more pronounced in men (February-September; IRR 0.88-0.95), whereas in women the changes were weaker and mainly limited to summer months (June-August; IRR 0.94-0.97), with a slight increase observed in February. During the COVID-19 pandemic, prescription numbers decreased significantly. Transitions between standard and daylight saving time exerted measurable short-term effects on sleep-related health at the population level. Conclusions: Based on data from a single primary care center in Poland, prescribing patterns for hypnotic and sedative medications demonstrate clear seasonality and significant gender differences. Longer daylight exposure and transitions to daylight saving time are associated with lower prescription rates. The COVID-19 pandemic substantially disrupted previous trends in sleep medication prescribing, which may be related to reduced access to healthcare services and changes in healthcare delivery. In addition, transitions between standard and daylight saving time were associated with statistically significant short-term changes in prescription rates.
