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
STUDY
objectivesWhile nocturnal hypoxia caused by sleep-disordered breathing (SDB) can result in polycythemia, the association between erythrocyte values and SDB may vary by sex and menopausal status. This study aimed to evaluate the correlation of erythrocyte variables with SDB in a large cohort categorized by sex and menopausal status from the general population.
methodsSleep duration and SDB were assessed in community residents using a wearable actigraph and pulse oximeter. The actigraph-adjusted 3% oxygen saturation index was calculated by correcting the time measured by the pulse oximeter for sleep duration computed by the actigraph. SDB severity was defined by actigraph-adjusted 3% oxygen saturation index as normal (< 5 events/h), mild (5 to < 15 events/h), and moderate to severe (≥ 15 events/h).
resultsData were obtained from 6,836 participants (premenopausal females, 1,580; postmenopausal females, 3,058; and males, 2,198). Multivariate analysis revealed that actigraph-adjusted 3% oxygen saturation index was negatively correlated with hemoglobin level in premenopausal females (β = -0.13,
conclusionsSDB was associated with microcytic anemia in premenopausal females. When SDB is diagnosed in a premenopausal female, we may need to evaluate her erythrocytic parameters.
