Statistics with Confidence is a widely acclaimed classic introduction to confidence intervals. The second edition, with contributions from leading medical statisticians, has been thoroughly revised and expanded. New chapters include: * diagnostic studies. * clinical trials and meta analyses. * confidence intervals and sample sizes. The Windows computer software (CIA) in the accompanying disk enables confidence intervals to be calculated using the methods described in the book. This comprehensive collection of methods includes some that are not readily available elsewhere.

Animated desktop screenmates performance. I don’t think screenmates were compatible with Macs, since they were usually.exe files, but I wouldn’t mind having a play with one again! I’ve actually found a blog that links to a (including Silver Cat and FaFa Cat) so you can go ahead and download them if you’re on a Windows system.:D If you want to download my favourite Favour Cat, you can visit. Have you ever heard of screenmates or deskmates? It rarely became a distraction.

Featuring methods for using confidence intervals, illustrative worked examples and helpful checklists this is a truly practical guide for clinical readers to a fundamental aspect of medical statistics.

Significance testing was two sided at the 5% level. We used the software package SPIDA.13 Relative risk and confidence intervals were calculated with CIA software.14 The study was approved by the national ethics committee.

Methods This retrospective cohort study involved 152 patients with ALI enrolled in the Fluid and Catheter Treatment Trial (FACTT) from five NHLBI ARDS (Acute Respiratory Distress Syndrome) Network sites. VPW and central venous pressure (CVP) or pulmonary artery occlusion pressure (PAOP) from the first four study days were correlated. The relationships between VPW, positive end-expiratory pressure (PEEP), cumulative fluid balance, and PAOP were also evaluated.

Receiver operator characteristic (ROC) curves were used to determine the ability of VPW to detect PAOP. Results A total of 71 and 152 patients provided 118 and 276 paired VPW/PAOP and VPW/CVP measurements, respectively. VPW correlated with PAOP (r = 0.41; P.

The NIH NHLBI ARDS Network Fluid and Catheter Treatment Trial (FACTT) demonstrated that fluid management for patients with acute lung injury (ALI) using a protocol guided by intravascular pressure measurements from a central venous catheter (CVC) resulted in similar clinical outcomes compared to fluid management directed by measurements from a pulmonary artery catheter (PAC) [ ]. The PAC group experienced significantly more nonfatal complications, mostly in the form of arrhythmias. These results, combined with previous studies demonstrating either lack of benefit or increased harm, have led many experts to discourage the routine use of the PAC in patients with ALI [, ]. Regardless of the type of catheter, a conservative fluid management strategy in ALI patients increased the number of days alive and free from mechanical ventilation [ ]. Central venous pressure (CVP) or pulmonary artery occlusion pressure (PAOP) was used to generate instructions and function as targets for the fluid management strategies in this trial.
