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

backgroundObstetric brachial plexus palsy (OBPP) may result in lifelong shoulder dysfunction despite nerve repair surgery. Tendon transfer has emerged as a surgical option to restore external rotation and abduction in OBPP sequelae. Single and double tendon transfer techniques have been developed, but the optimal approach remains debated. This meta-analysis is the first to compare the range of motion outcomes and complications, particularly loss of midline function (LOM), between the two techniques in managing OBPP sequelae.

methodsOn January 2025, systematic literature search was performed in five databases (PubMed, Cochrane Library, Embase, Scopus and Web of Science), to identify studies comparing single and double tendon transfer in children with OBPP. Eligible studies underwent quality assessment via MINORS criteria and a meta-analysis using RevMan was conducted to compare the functional outcomes and complications.

resultsFive retrospective studies encompassing 189 patients were analyzed. The pooled mean difference (MD) in the total modified Mallet score between groups was statistically insignificant (MD = 0.09; 95% CI= -0.68 to 0.85;p > 0.05). Analyses for the sub-scores revealed no differences across all sub-scores. However, for Latissimus Dorsi (LD) single transfers, Abdel-Ghani et al. reported 7.7-fold greater odds of LOM (OR = 0.13; 95% CI = 0.04-0.42;p < 0.05), whereas the pooled LOM of Teres Major (TM) single transfers were not significantly different (OR = 0.40; 95% CI = 0.11-1.47;p > 0.05).

conclusionIn conclusion, our meta-analysis suggests that both single and double tendon transfers achieve comparable functional outcomes. However, the data suggests that LD single tendon transfer potentially lowers rate of LOM, though further research is needed to confirm this finding. CLINICAL TRIAL NUMBER: Not applicable.
