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

backgroundThe hemocyte profile is a frequently requested clinical laboratory test. However, the analysis of blood cell indexes of obstructive sleep apnea (OSA) patients in previous studies was not decisive. This study aimed to fully analyze the blood count patterns in OSA patients.

methodsWe retrospectively studied 114 patients, referred to the sleep center of Nicosia General Hospital in Cyprus and had sleep studies performed from July 2022 until October 2024. Based on apnea hypopnea index (AHI), patients were divided into four groups: control (AHI < 5, n = 12), mild OSA (5 ≦ AHI < 15, n = 35), moderate OSA (15 ≦ AHI < 30, n = 28), and severe OSA (AHI ≧ 30, n = 39). We evaluated sleep parameters by type III with Nox T3s home sleep testing device. Patients with central sleep apnea syndrome, chronic respiratory failure and known haematological diseases were excluded.

resultsSignificant positive linear correlations of hematocrit, hemoglobin and red blood cells (RBC) with oxygen desaturation index (ODI) were observed, and inverse linear correlations with minimum SpO2. There was a significant positive linear correlation between hematocrit and duration SpO2 < 90%, but not with average SpO2. The values of mean platelet volume (MPV) had statistically significant positive linear correlations with ODI and minimum SpO2.

conclusionsOur results indicate that subjects with severe OSA had higher hematocrit levels than subjects with no OSA or mild to moderate OSA. Even though MPV is associated with a higher degree of nocturnal hypoxemia, among the laboratory parameters that were investigated, only hematocrit can be used as an inexpensive tool for triaging OSA patients for evaluation in sleep laboratories.
