Patient specific instrumentation.
Trial report in The Journal of arthroplasty, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 1 of them a synthesis that pooled 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.
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
Patient specific instrumentation (PSI) has recently been developed as a replacement for traditional instrumentation in total knee arthroplasty (TKA). The study aim was to assess efficiency via the mean total OR time using the PSI versus computer-assisted (CAS) TKAs with accuracy as a secondary endpoint. Sixty patients were randomized to CAS or PSI. A formula was developed to derive a profit ratio (PR) that incorporated costs, revenue, and total OR time. The PSI cases were 1.45 times more profitable than CAS allowing for approximately 3 PSI cases versus 2 CAS cases in one 8 hour OR day. Results from this series show that PSI improves OR efficiency, but does not improve accuracy.
