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
Plastic surgeons are frequently consulted to perform temporal artery biopsy (TAB), even though patients meet the American College of Rheumatology diagnostic criteria for giant cell arteritis (GCA) and are already treated. This study aimed to analyze the impact of TAB on steroid duration in patients undergoing TAB. Methods: We undertook a prospective study of adult patients undergoing TAB for GCA in Calgary. Consecutive, multicenter recruitment was performed over 2 years. Primary outcomes included initiation or discontinuation and duration of corticosteroids. Results: Twenty-one TABs were performed in 20 patients. Nineteen percent of TABs were positive, and 71.4%, negative. In 9.5% of patients, accidental sampling of a vessel other than the superficial temporal artery occurred. Fifty-two percent of patients received steroids before TAB, of which the mean duration was 8.0 days for TAB+ (postive temporal artery biopsy result) patients and 8.4 days for TAB- (negative temporal artery biopsy result; Conclusion: In patients with a low suspicion of GCA, a negative TAB helps bolster physician confidence and leads to a shorter steroid duration.
