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

objectivePerformance of safe central neuraxial blocks requires identification of accurate vertebral interspace. This study aimed to evaluate the accuracy of palpation method by confirmation with ultrasound in high-risk groups like obesity and pregnancy.

methodsThis cross-sectional comparative study was conducted after approval from the hospital ethics committee and written informed consent from participants. Participants were enrolled into four groups: normal weight non-pregnant (N), full-term pregnant (P), obese (O) and obese full-term pregnant (PO). Tuffier's line at L4-L5 interspace was determined by palpation method and marked as P-line. Another examiner blinded to the marking done by palpation method confirmed it by ultrasound. The primary endpoint was to determine the accuracy of the palpation method, defined as true identification of Tuffier's line at the L4-L5 interspace by confirming it with ultrasound among four groups. Proportion and percentage were computed and analysed the true identification of Tuffier's line at L4-L5 by chi-square test at 0.008 adjusted level of significance for multiple comparisons.

resultsTuffier's line identification by palpation method was confirmed by ultrasound scanning at L4-L5 interspace in 75.3% (226/300) of participants. Proportion difference of true identification of Tuffier's line at L4-L5 by palpation and ultrasound was statistically significant among the groups (p=0.0005). True identification was significantly lower in group PO [36.4%; p=0.0005<0.008] and group O [34%; p=0.0005<0.008] as compared to that in group N.

conclusionPalpation method was found to be the inaccurate surrogate for the L4-L5 vertebral interspace for obesity with or without pregnancy.
