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
REM (rapid eye movement) sleep deprivation causes serious impairments in hippocampus-dependent learning and memory. This study examined whether the angiotensin II receptor blocker telmisartan, given at two different doses, could reduce cognitive deficits and affect molecular pathways related to chronic REM sleep deprivation. Thirty-two male Wistar-Albino rats (200-280 g, 3 months old) were randomly divided into four groups (n = 8): control, sleep deprivation (SD), telmisartan-treated SD groups at 1 mg/kg (SD+Tel1) and 3 mg/kg (SD+Tel3). Chronic REM sleep deprivation was induced for 21 days using the modified multiple platform (MMP) method. Telmisartan or distilled water was administered orally once daily. Cognitive performance was tested in the Morris water maze, assessing escape latency and time spent in the target quadrant. After behavioral tests, hippocampal and prefrontal cortex samples were analyzed for brain-derived neurotrophic factor (BDNF), cAMP response element-binding protein (CREB), glycogen synthase kinase-3 beta (GSK-3β), monocarboxylate transporter 2 (MCT2), and lactate dehydrogenase (LDH) levels, while plasma samples were analyzed for corticosterone (CORT) levels. Brain levels of malondialdehyde (MDA), reduced glutathione (GSH), nitrate, and glycogen were also measured. Sleep-deprived rats showed impaired learning and memory with longer escape latency and reduced time spent of target quadrant. Telmisartan-treated SD groups demonstrated significantly improved cognitive performance, increased BDNF and CREB expression, decreased GSK-3β levels, and balanced oxidative stress markers. In conclusion, telmisartan protected against cognitive and biochemical damage caused by chronic REM sleep deprivation, likely through modulation of GSK-3β/CREB/BDNF signaling and reduction of oxidative stress.
