Risk factors in cutout of sliding hip screw in intertrochanteric fractures: an evaluation of 937 patients.
Trial report in International orthopaedics, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued.

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.

Abstract
The aim of this study was designed to assess the risk factors of lag-screw cutout in the treatment of intertrochanteric fracture with a dynamic hip screw (DHS). From 2003 to 2007, 1,150 patients who had acute unilateral intertrochanteric fractures of the femur were enrolled to the study. All fractures were managed by closed reduction and internal fixation with 135° DHS devices. Patient demographics, fracture patterns, reduction and fixation and perioperative course parameters were all recorded. The follow-up period was 38 months on average (range 16-60 months). Finally, 937 patients were available for evaluation of final results in which we focused on lag-screw cutout. Excluding complications not related to screw position, 64 patients (6.8%) with screw cutout were encountered, and the remaining 873 patients had uneventful union, with the average union time of 17.5 weeks (range15-24 weeks). Upon analysis with logistic regression, the tip-apex distance (TAD) was shown to be the most important predictive factor for cutout, followed by screw position, fracture pattern, reduction and patient age. In order to decrease the risk of lag-screw cutout, it is important to ensure good fracture reduction and to place the lag screw in either the middle/middle or inferior/middle position with appropriate TAD.
