Serum Total Cholesterol and Fatal Subarachnoid Hemorrhage in 120,000 Japanese: A Pooled Analysis of Data from 12 Cohorts.

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
aimThe aim of this study was to clarify the association between serum total cholesterol and fatal subarachnoid hemorrhage in Japanese men and women.
methodsThe study involved a pooled analysis of individual data from 12 well-qualified cohort studies conducted in Japan. The participants were classified according to their serum total cholesterol levels: ＜4.14 mmol/L (＜160 mg/dL), 4.14-4.64 mmol/L (160-180 mg/dL), 4.65-5.16 mmol/L (180-199 mg/dL), 5.17-5.68 mmol/L (200-219 mg/dL), 5.69-6.20 mmol/L (220-239 mg/dL), and ≥ 6.21 mmol/L (≥ 240 mg/dL). The outcome of the analysis was death from subarachnoid hemorrhage.
resultsA total of 120,973 participants (70,947 women and 50,026 men) aged 18-96 years at baseline underwent follow-up for a median of 12.7 years, and 261 participants died from subarachnoid hemorrhage during this period. In women, both low (＜5.69 mmol/L [＜220 mg/dL]) and high (≥ 6.21 mmol/L [≥ 240 mg/dL]) serum total cholesterol levels were significantly associated with a higher risk of fatal subarachnoid hemorrhage compared with the reference group (5.69-6.20 mmol/L [220-239 mg/dL]). These associations remained significant after adjustment for confounding factors. In contrast, no associations were observed in men.
conclusionBoth low and high serum total cholesterol levels were associated with a higher risk of fatal subarachnoid hemorrhage in 70,947 female participants from 12 cohort studies throughout Japan.
