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

introductionSecondary brain injury due to increased intracranial pressure (ICP) contributes to post-traumatic morbidity and mortality. Although it is often taught that increased ICP begins early after traumatic brain injury, some patients develop increased ICP after the first 3 days post-injury. We examined our data to describe temporal patterns of increased ICP.

methodsThis is a retrospective review of prospectively collected physiologic and demographic data.

resultsSeventy-seven patients were included. We identified four patterns of increased ICP: beginning within 72 h (early), beginning after 72 h (late), early increases with resolution, and then a second rise after 72 h (bimodal), and continuously increased ICP. Late increases in ICP occur in 17% of this cohort. Peak day of swelling was day 7 for the "late" rise group and day 4 for the other patients with increased ICP. Forty-four percent of patients showed enlargement of cerebral contusions on follow-up imaging at 24 h post-injury.

conclusionsLate rises in ICP were not rare in this cohort. This is clinically relevant as it may impact decisions about ICP monitor removal. Differences between groups in age, CT patterns of injury, fluid therapy, osmotic use, and fever were not statistically significant.
