1 · What the graph read from 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.

2 · The registry

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

purposeThere is no consensus on the optimal operative technique for humeral shaft fractures. This meta-analysis aims to compare minimal-invasive plate osteosynthesis (MIPO) with nail fixation for humeral shaft fractures regarding healing, complications and functional results.

methodsPubMed/Medline/Embase/CENTRAL/CINAHL were searched for randomized clinical trials (RCT) and observational studies comparing MIPO with nailing for humeral shaft fractures. Effect estimates were pooled across studies using random effects models and presented as weighted odds ratio (OR), risk difference (RD), mean difference (MD) and standardized mean difference (SMD) with corresponding 95% confidence interval (95%CI). Analyses were repeated stratified by study design (RCTs and observational studies).

resultsA total of 2 RCTs (87 patients) and 5 observational studies (595 patients) were included. The effects estimated in observational studies and RCTs were similar in direction and magnitude for all outcomes except operation duration. MIPO has a lower risk for non-union (RD 7%; OR 0.2, 95% CI 0.1-0.5) and re-intervention (RD 13%; OR 0.3, 95% CI 0.1-0.8). Functional shoulder (SMD 1.0, 95% CI 0.2-1.8) and elbow scores (SMD 0.4, 95% CI 0-0.8) were better among patients treated with MIPO. The risk for radial nerve palsy following surgery was equal (RD 2%; OR 0.6, 95% CI 0.3-1.2) and nerve function recovered spontaneously in all patients in both groups. No difference was detected with regard to infection, time to union and operation duration.

conclusionMIPO has a considerable lower risk for non-union and re-intervention, leads to better shoulder function and, to a lesser extent, better elbow function compared to nailing. Although nailing appears to be a viable option, the evidence suggests that MIPO should be the preferred treatment of choice. The learning curve of minimal-invasive plating should, however, be taken into account when interpreting these results.
