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

objectivesTo describe the clinical features and possible etiologies of cerebral vein thrombosis (CVT) in a Saudi Arabian cohort.

methodsA retrospective, observational design was implemented. Data pertaining to 36 patients (19 female and 17 male) with confirmed CVT diagnosis admitted to a hospital in Saudi Arabia between 2008 and 2019 were obtained and analyzed.

resultsThe age of patients ranged between 19 to 82 years, and the mean/median age was 33/29 years. Most commonly reported symptoms were headache ( 72%), unilateral lower limb weakness (39%), and seizures (17%). Papilledema was found in 8% of patients. Thrombotic disorders were identified in 14% and infections were identified in 8% of the patients. Two patients had ulcerative colitis, 2 were diagnosed with Behcet's disease, and 2 women were using oral contraceptive pills. Single sinus thrombosis was detected in only 22% of patients. One patient with diabetic ketoacidosis died. Thrombotic disorder was the most common risk factor, followed by that iron deficiency anemia.

conclusionThe transverse sinus was the most frequently thrombosed sinus. Iron deficiency anemia emerged as a predisposing preventable condition for CVT, while genetic factors were found to be less important in this cohort.
