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

objectiveIn one study, higher serum melatonin levels have been reported at diagnosis of spontaneous intracerebral hemorrhage (ICH) in non-surviving than in surviving patients. Now, we carried out this study with the aims to explore whether blood melatonin concentrations in the first 7 days of ICH are different in survivor and non-survivor patients and whether are useful in the prediction of mortality.

methodsSix Spanish hospitals participated in this observational study of patients with severe supratentorial ICH (defining severe as Glasgow Coma Scale < 9). We determined serum melatonin levels during the first, fourth, and eighth day of severe ICH.

resultsSurviving (n = 64) compared to non-surviving (n = 53) patients showed lower serum melatonin levels during the first (p < 0.001), fourth (p < 0.001), and eighth day (p < 0.001) of severe ICH. We found in multiple logistic regression analysis an association between serum melatonin levels and 30-day mortality (odds ratio = 8.932; 95% CI = 2.442-32.665; p = 0.001) controlling for midline shift, ICH score, early evacuation of ICH, and glycemia. We found an AUC (95% CI) for the mortality prediction of 0.90 (0.83-0.95; p < 0.001), 0.94 (0.87-0.98; p < 0.001), and 0.90 (0.81-0.96; p < 0.001) by serum melatonin concentrations during the first, fourth, and eighth day.

conclusionsIn our current study, it appears that novel findings of serum melatonin levels recollected at any moment during the first 7 days of a severe ICH were higher in non-survivor than in survivor patients and could help in mortality prediction.
