Nerve blocks (subcostal, lateral cutaneous, femoral, triple, psoas) for hip fractures.
Synthesis in The Cochrane database of systematic reviews, 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundVarious nerve blocks using local anaesthetic agents have been used in order to reduce pain after hip fracture.
objectivesTo determine the effects of nerve blocks (inserted either pre-operatively, operatively or post-operatively) as part of the treatment for a hip fracture. SEARCH STRATEGY: The Cochrane Musculoskeletal Injuries Group specialised trials register, MEDLINE, and bibliographies of trial reports were searched. Date of the most recent search: October 2000. SELECTION CRITERIA: Randomised and quasi-randomised trials involving the use of nerve blocks as part of the care of a hip fracture patient. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality, by use of a nine item scale, and extracted data. Wherever appropriate, results of outcome measures were pooled. MAIN
resultsSeven randomised or quasi-randomised trials involving 269 patients were included. Two trials related to insertion of a nerve block pre-operatively and the remaining five to peri-operative insertion. Nerve blocks resulted in a reduction of the quantity of parenteral or oral analgesia administered to control pain from the fracture/operation or during surgery and a reduction in reported pain levels. It was not possible to demonstrate if this reduction in analgesia use was associated with any other clinical benefit. REVIEWER'S
conclusionsBecause of the small number of patients included in this review and the differing type of nerve blocks and timing of insertion, it is not possible to determine if nerve blocks confer any significant benefit when compared with other analgesic methods as part of the treatment of a hip fracture. Further trials with larger numbers of patients and full reporting of clinical outcomes would be justified.
