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

Previous research suggests that dietary intake and blood levels of fatty acids may influence the risk of osteoporosis and hip fractures, although findings have been inconsistent. We conducted a meta-analysis of nine prospective cohort studies involving 382,094 participants and 12,392 hip fractures to investigate these associations. Follow-ups ranged from 7 to 24 years in duration. A hazard ratio (HR) of 1.20 (95% CI: 1.08-1.33) indicated that a higher intake of saturated fatty acids (SFAs) was associated with an increased risk of hip fractures. In contrast, polyunsaturated fatty acids (PUFAs) (HR: 0.93; 95% CI: 0.85-1.00) and linoleic acid (LA) (HR: 0.89; 95% CI: 0.82-0.96) were associated with a lower risk, though the PUFA association was marginal. The inverse relationship for LA was observed only at intakes of 9-16 g per day. Higher amounts of PUFAs (HR: 0.75; 95% CI: 0.61-0.92), total omega-3 fatty acids (HR: 0.79; 95% CI: 0.64-0.97), and eicosapentaenoic acid (EPA) (HR: 0.76; 95% CI: 0.62-0.94) in the blood were linked to a lower risk. No significant associations were found for other fatty acids. These findings suggest that consuming 9-16 g of linoleic acid (LA) daily (equivalent to 2-3 tablespoons of corn oil or 30-60 g of walnuts) and maintaining elevated blood levels of omega-3 fatty acids, especially eicosapentaenoic acid (EPA), may help reduce the risk of hip fractures.
