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.

Abstract

backgroundJapan is the first country in the world to approve tolvaptan for the treatment of autosomal dominant polycystic kidney disease (ADPKD), which was based on the results of Tolvaptan Efficacy and Safety in Management of Autosomal Dominant Polycystic Kidney Disease and Its Outcomes (TEMPO) 3:4 trial. To evaluate the safety and efficacy of tolvaptan, we performed a subgroup analysis in the participating Japanese ADPKD patient population.

methodsThe primary outcome was the annual rate of percentage change in the total kidney volume (TKV). The secondary endpoint was the rate of kidney function change.

resultsThe tolvaptan and placebo groups included 118 and 59 patients, respectively. The annual rate of percentage changes in TKV were 1.3 % [95 % confidence interval (CI) 0.4-2.1] in the tolvaptan group, and 5.0 % (95 % CI 3.9-6.2) in the placebo group (P < 0.001). The annual estimated glomerular filtration rate change was -3.83 mL/min/1.73 m(2) in the tolvaptan group and -5.05 mL in the placebo group for a treatment effect of +1.22 mL/min/1.73 m(2) (95 % CI 0.41-2.02: P = 0.003). Hepatic function abnormal as a serious adverse event was observed in 3 patients (2.5 %) in the tolvaptan group.

conclusionsAdministration of tolvaptan in the Japanese sub-population reduced the annual rate of TKV growth and slowed the rate of kidney function decline over 36 months compared to patients on placebo, thus providing a novel and effective therapy for the treatment of ADPKD. (TEMPO 3:4 ClinicalTrials.gov number, NCT00428948).
