1 · What the graph read from 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.

2 · The registry

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

backgroundInsomnia continues to be neglected globally, despite its high prevalence. Guidelines by the health regulatory agencies call for studies to evaluate the effect of sedative-hypnotics on sleep quality.

methodsWe conducted a pre-post observational study to evaluate sleep quality among 186 inpatients receiving short-term oral sedative-hypnotic therapy in a tertiary care teaching hospital in Kozhikode (Kerala), India. Using Pittsburgh Sleep Quality Index_Past-Week (PSQI_PW) questionnaire, patients were interviewed upon hospital admission and at follow up after ≥1-week of sedative-hypnotic therapy. Additionally, we interviewed 36 physicians to understand the current clinical perception about sedative-hypnotics.

resultsMean (SD) age of the study patients was 59 (7.5) years. Majority (63.4%) of the patients were men. Of the various primary diagnoses for hospitalization, cardiovascular disease was the most common (22.6%, n = 49). Sedative-hypnotic therapy improved the mean (SD) PSQI_PW overall score by 6.79 points (pre: 12.70 (3.5) vs. post: 5.91 (2.8); p < 0.0001). Statistically significant improvements in sleep duration, latency, efficacy, and day dysfunction were observed. Higher proportion of study patients were prescribed benzodiazepines (73.7%) compared to zolpidem (26.3%). Patients treated with zolpidem reported higher improvements in mean overall PSQI_PW scores compared to those treated with benzodiazepines, however these differences were not statistically significant upon adjusting for age, gender and primary diagnosis for hospitalization. Qualitative interviews indicate that that physicians consider zolpidem to be safer and more efficacious.

conclusionsIn our study, sedative-hypnotic therapy helped improve sleep quality among the hospitalized patients. More studies evaluating the comparative efficacy and safety of zolpidem vs. benzodiazepines - including among patient groups with varying demographic and clinical characteristics - are needed. India must develop evidence-based treatment guidelines to inform the clinical practice around the use of sedative-hypnotics.
