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

Objectives: The primary objective was to compare the hypnotic efficacy of oral melatonin, oral L-theanine, and placebo in improving sleep in cancer patients with insomnia by the Athens Insomnia Scale (AIS). The secondary objective was to know the prevalence of insomnia in patients with cancer. Materials and Methods: A prospective, double-blinded, placebo-controlled study was conducted after obtaining Institutional Ethics Committee approval. One hundred and twenty patients were randomly assigned to either Group A (melatonin), Group B (L-theanine), or Group C (placebo). They were instructed to take the tablets for 14 consecutive days, two h (hours) before bedtime, and evaluated with AIS on the 1 Results: There were seven dropouts: Two in Group A, two in Group B, and three in Group C. Significant differences in favour of melatonin treatment were found. There were statistically significant improvements in insomnia in cancer patients on melatonin intake compared to L-theanine. L-theanine had statistically significant improvements in insomnia in comparison to placebo. The mean ± standard deviation AIS on day one in Group A was 14.82 ± 1.29; on day seven was 10.92 ± 1.12; and on day 14 was 5.00 ± 0.70. Similarly, in Group B, the mean ± standard deviation AIS was 15.39 ± 1.03, 13.05 ± 1.06, and 9.55 ± 1.01, and in Group C, the mean AIS was 14.92 ± 1.40, 14.54 ± 1.35 and 13.05 ± 1.61 on the 1 Conclusion: The hypnotic efficacy of oral melatonin 3 mg was better than oral L-theanine 200 mg in cancer patients having insomnia. Furthermore, L-theanine had a better hypnotic efficacy when compared to a placebo.
