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

introductionHyperthermia following a severe traumatic brain injury (TBI) is common, potentiates secondary injury, and worsens neurological outcome. Conventional fever treatment is often ineffective. An induced normothermia protocol, utilizing intravascular cooling, was used to assess the impact on fever incidence and intracranial pressure (ICP) in patients with severe TBI.

methodsA comparative cohort study of 21 adult patients with severe TBI (GCS <or= 8) treated with induced normothermia [36-36.5 degrees C rectal probe setting; intravascular cooling catheter (CoolLine, Alsius Corporation, Irvine, CA)] were matched by age, gender, and severity of injury to 21 historical control severe TBI patients treated with conventional fever control methods. ICP was measured via an external ventricular catheter and time duration for ICP > 25 mmHg was calculated for the initial 72-h monitoring period. Non-parametric rank tests were performed.

resultsMean (+/-SD) or median [range] demographics did not differ between groups [total N = 42 (6 female, 36 male, age 36.4 +/- 14.8 years and initial GCS 7 [3-8], median and range]. Fever burden in the first 3 days (time >38 degrees C) in the induced normothermia versus control group was significantly less at 1.6% versus 10.6%, respectively (P = 0.03). Mean ICP for patients with induced normothermia versus control was 12.74 +/- 4.0 and 16.37 +/- 6.9 mmHg, respectively. Furthermore, percentage of time with ICP > 25 mmHg was significantly less in the induced normothermia group (P = 0.03).

conclusionInduced normothermia (fever prophylaxis via intravascular cooling catheter) is effective in reducing fever burden and may offer a means to attenuate secondary injury, as evidenced by a reduction in the intracranial hypertension burden.
